Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

I need to set up a virtual machine for new software.
I received software CPU requirements:
2 GHz or more
Xeon quad-core server grade processor

I am planning to set up the following:
Windows Server 2016 Standard
Number of virtual sockets: 2
Number of cores per socket: 2
Total number of cores: 4

I am pretty sure that Windows Server 2016 Standard - License comes as a 2-core license at the price of  CAD $1,099.56.
Based on my virtual machine setup mentioned above do I need to purchase 2 of these for the future audits?
Also, if someone has any additional details/advice on current licensing process please let me know. I need to upgrade all of my Windows Server 2008 R2 servers to 2016.

Thanks for your help, much appreciated.

Hi All,

I need to power off everything at work while an electrical test is performed.

We have two ESX 5.5 servers that are managed by vCenter,

I'd like to do the power off and back on remotely (there is someone onsite to switch the power back on, but they cant do anything else).

Is there a way to get the server to take itself out of maintenance mode and auto start a VM?  As the VPN relies on one of the VMs.


Many thanks

Hi All,

I have two ESX 5.5 servers that share data on two SANs.  I need to power everything off to perform an electrical test.

Last time i powered off the ESX servers by shutting down all the VM's manually (logging in and clicking shutdown).  then i click ed on the ESX and shut it down.  But it failed all the shutdown VM's to the other ESX.  Which i had to manually move back when the server came back online.

Is there a better way to shutdown vCenter 5.5?


Many thanks

Hi all,

Just a quick question on a big subject and would like some thoughts...

I have a server I plan to use as a basic Hyper-V host and I don't know how many virtual processors to allocate across the VM's

The Host has two XEON 8 Core Hyperthreaded CPU's and plenty of RAM, I would like to know how many vCPU's that equates to roughly

I plan to run two Exchange servers in a DAG and would like recommendations for how many to allocate each of them? There will also be a number of Server 2016 and 2012R2 machines running various small loads and some Windows 7 and 10 clients.

I have read all sorts of conflicting answers and I'm unsure of what to do.

Thanks for reading and participating in this question.

Hi,

I d like to run an esxi on low hardware, just for 1 or 2 vm s (HP Microserver). Is there a wat to configure the vms without the need of VCenter?  Or I might run Hyper-V but not sure if XPENology runs on it and there is a management interface like VCenter(?) for Hyperv?

I upgraded the VMWare Tools on a Redhat 5.7 server after which the NIC stopped working, no ping or SSH. I went via the vm console and uninstalled the vmware tools which after a reboot allowed the server to communicate again, how do I go back to the original (old) vmtools?

I have found packages.vmware.com but I have no idea which rpm files I need to run on the machine to get a working vmtools installation.

Hello Sir,

I have 5 years experience as  an IT Assistant Manager in business level infrastructure management.
Now i want to change the job, For that i need to choose one best path.  

From Current technologies i love VMware and Exchange server domains. In VMware i have 50% knowledge but i don't have the experience in that domain. in Exchange server i have 50% Knowledge with experience.

But this is the time to choose one best path and get trained and do the certification. But i'm fully confused to choose the path. Because both are the best growing technologies and best in the market.

So please suggest me if i go with two . is it worthy or should i chose any one. If i need to choose one. Please suggest your opinion and explain the Pros and Cons.


i am waiting for your valuable suggestions

Network LayoutHi,

 I have VMWare box that came with two NICs. I use one NIC for internal servers and workstations and they are on 192.168.1.x network.
 The 2nd NIC is directly connected to the back of ISP internet modem for the virtual machiens that need direct connection to the internet by getting public dynamic IP addresses from ISP DHCP server and it has been working fine.
 Recently these virtual machines (under "Public IP -vSwitch1") fails to receive public IP from ISP's DHCP server. If I assign a static public IP (we have a set of 5 public IPs given by ISP) to these VMs, they work fine. However if I configure TCP/IP properties in these VMs to receive IP dynamically, it receives 192.168.1.x number as if it is under vSwitch0.
 Today I spoke to tech support at ISP and they confirmed that they still give out dynamic IP addresses to any device attached to their internet modem as long as it is set to receive dynamic IP.
So far, I have restarted these VMs, switched NIC between vSwitch0 and vSwitch1 on VMs, shutdown & start, even created a new virtual machine and assigned NIC to vSwitch1/Public IP group, but to no avail.
I have not restarted VMWare box yet.

 Any suggestions?

Thanks.

Hi,

Is there a lightweight Ubuntu distro (like Ubuntu, but which version then), which can run with little resources (CPU/Memory)?

Might then run it (not sure if I will go for XPenology on HP Microserver yet  -what bugs me there is the uncertainty of upgrades and funcationality-) on a Synology DS918+ virtual machine manager (this Synology has only 4 GB of ram by default and processor is basic).
The idea is to have some users in my family use this distro and be able to do everything you can on a W10 + have fast access to data (since vm is running on Synology itself). Via RDP or via the webinterface of Synology.

Thanks for your input.

Hello EE,

In my VM environment, we have a new storage system that tells us via reporting systems with less than 20% memory and CPU utilization.  The reports recommends to regain resources to lower these.  I understand the lowering memory, but for CPU, is there risk with lowering Cores per Sockets or Sockets (I'm not sure the difference) if I have 2 on both and they suggest going to 1

we use citrix profile management so our users of approx. 600 all have a citrix UPM roaming profile which resides on a windows file server. I have spotted that each users profile is accessible by the domain users security group so in theory if users new where they were they could look into each others. I am wondering though would there ever be any sensitive information in a UPM profile, it mainly just seems to be certain logs from user applications, which I guess could show browsing history. So I am leaning towards it being less of a risk unless of course anyone could think of any other examples of the type of info that would reside in users UPM profile,

Hi,

I am using VMware Workstation 14 and I have a virtual hard disk .vmdk with C drive having only 40 GB free space.

Is it possible to increase the C drive size in the .vmdk VMWare Workstation 14 version .vmdk virtual disk file?

Please reply to this question asap.

Thanks for your support.

Warm Regards,

Hi,

Could somebody advise on building a Synology nas on a HP Microserver?

What server to buy, could I just migrate my 4 disks from my ds414 to it ...?

Found this but no real guide to implement or where to download the latest versions (which I would need to virtual machine manager)

Hi there,

I'm trying to dynamically create this string in a variable so that I can then run "eval" on it and run the command remotely on another Linux VM.

ssh oracle@10.41.22.69 "md5sum /data/oracle/dpdump/onegeo/ONEGEO20171214.DMP | awk '{ print \$1 }'"

I can get the string working until the "awk" part and then no matter what I try, I keep getting errors when trying to properly create the rest of the string with single quotes.  The double and single quotes in the string are all required.  

I tried this but it didn't work, what am I missing?
md5command='ssh oracle@10.41.22.69 "md5sum /data/oracle/dpdump/onegeo/'$DMPfilename' | awk '\'{ print \$1 }\''

Any help would be appreciated!!

Thanks,
- Christian

Hi,

I posted this some time ago:
https://www.experts-exchange.com/questions/29074817/Synology-NAS-DS-1817-32GB.html

have a DS414 now, didn't buy a new one yet, since it was quite some money to spend for "just a home lab".

Now I've read that the Synology DS918+ (reviews are pretty good):
*only costs 550 Euro
*has quad core 1,5 Ghz, https://www.cnet.com/products/synology-disk-station-ds918-plus-nas-server-0-gb/specs/)
*also runs 16 GB (about 150 Euro for 16 GB)
https://forum.synology.com/enu/viewtopic.php?t=136028 has SSD cache built in
*is only using 100 Watt
*has SSD cache build in (without the need to buy an extra card)
*can run virtual machine manager: https://www.synology.com/nl-nl/dsm/packages/Virtualization

My current NAS = DS414 with 4 disks (Seagate Green -no SSD- basic disks) of 3 TB in RAID5 (still half of it is empty).
So I'm thinking of buying this DS918+ and buying 16 GB for about 160 Euro
=> crucial-8gb-ddr3l-1600-cl11-sodimm

Not sure about the SSD cache: would I need it and if yes which one and how much storage (128, 250 GB ...? they are quite expensive):
https://www.synology.com/en-uk/compatibility?search_by=products&model=DS918%2B&category=hdds&filter_type=M.2%20NVMe%20SSD&p=1 

As mentioned, it is only for home use (1 user and running a vm from time to time), maybe other users will connect remotely and I might run a website on it.
So I'd spend 700 Euro for this upgrade. That's about the max I wanted to spend.

So please …

hi guys

I need to restore a file from a tape backup on Veeam. I can't for the life of me do it. I use Symantec so I am used to just being able to browse to the file location and restore.

How do you restore just one file from a tape backup?

Thanks for helping

Our Hyper-v machine had a power failure and some of the virtual machines are in a state of "Saved-Critical".  When I try to start them I get "failed to restore virtual machine state".  "failed to lock virtual machines configuration"

What do I do to get them started?

Hi all
I have a win2000 server running bespoke software that obviously needs to be retired, so I am hoping to create a vhd file of this machine & run it on a 2008R2 server.
Not having done this before I need advice on firstly, can this be done? & secondly how to step through what is required to do this. The Microsoft website is confusing, to say the least.
What software would I need etc. Disk2VHD won't work on 200 as there is no VSS.

Hoping some kind person might be able to enlighten me.

Regards

now I need to setup disaster recovery ,let said this server hardware failure .We can use Veeam to perform the bare metal recovery to another hardware.

Please advice how to setup above..

I would like to run guest operating systems in virtual machines under my Windows 10 environment. Specifically, I'd like to run older versions of Windows as well as Linux distributions. Currently I'm using VMware Player version 7.1.4 to run Windows 8.1 and openSuSE Linux (Leap 42.3) in virtual machines. I run the Linux operating system more often than I run Windows 8.1, and can't help but notice that when Linux is running in a virtual machine I'm experiencing a lot of performance issues. Specifically, the system will freeze for several minutes! During those freezes, most if not all of the applications on the desktop are unresponsive! I can't say this doesn't happen when I'm running Windows 8.1 in a virtual machine, but I don't run that environment as often. I don't know enough about VMware to know whether I've optimized its settings for running either environment. The settings for the virtual machine running Windows 8.1 are as follows:

Windows-8.1-1.png
Windows-8.1-2.png
The settings for the virtual machine running Linux are as follows:

Linux-1.png
Linux-2.png
If someone can recommend tweaks to these settings, I would appreciate it. For example, should I have any of the boxes under Processors checked?

I'm also willing to consider trying a different hypervisor. I know that Windows has one, and I've heard of something called Xen.

Hi all. Hopefully a no-brainer for someone.
I have my test 2012r2 VM in azure. I have gone to the VM > monitoring > metrics.
My question - If i select sub-service (please see added image) i get the option of switching between the Guest and Host. What does either mean in this context because i am using a vm guest, so why the host option - what's that exactly?
Thanks all.

I updated my ESXi from 5.1 to 6.5

I backed up all my VM's via Veeam Backup and Reoveray.

I detroyed my existing RAID set and re-created a new Virtual Disk.

I instaledl I upgraded my ESXi from 5.5 to 6.6licenses.

I instaled the OSMA

I'm just stuck on restoring my VM's.

I'm currently installing and deploying the new VCenter.

If anyone is awake, I could use some assistance in restoring the VM's from my Veeam Backup and Replication.

Thanks in advance for all the help.
