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.

The 7 Worst Nightmares of a Sysadmin

Fear not! To defend your business’ IT systems we’re going to shine a light on the seven most sinister terrors that haunt sysadmins. That way you can be sure there’s nothing in your stack waiting to go bump in the night.

Hello I've got a Virtual Machine which will not shutdown.  I've tried from Hyper-V Manager (Right Click, Shut Down).   It will not shutdown every-time get the following error:
"An error occurred while attempting to shutdown the virtual machine."
"Failed to stop"

Info is as follows:
Host = Dell Precision 7710, running Windows 10
Guest in question running Red Enterprise Edition

Not sure what to try.

How can we set our VMware hosts to be not fully managed by vCenter while still remaining connected to it?  Here's the background:

We have a number of VMware ESXi hosts running v6.0 and v6.5.  After we recently removed our last v5.1 host, we installed a new vCenter server appliance v6.7 to replace the existing v6.0 vCSA.

The problem comes with Altaro VM backup, which always backs up through vCenter if the host is connected to one.  Despite saying that the versions we're using are supported (http://support.altaro.com/customer/en/portal/articles/808716-what-are-the-system-requirements-for-altaro-vm-backup-) in fact the combination of vCenter >= v6.5 and hosts v6.0 is not supported (http://support.altaro.com/customer/portal/articles/2949256).

Now Altaro support suggested that it's possible to work around this by setting the hosts to not be fully managed by vCenter.  How do we do this?

The alternative is to downgrade the v6.5 hosts to v6.0 and use a v6.0 vCenter Server Appliance, which we'd rather not have to do as it means we can't use any hosts of v6.5 or later.

We plan to implement Splunk SIEM.

Q1:
As most of our servers are VMs (VMWare ESXi 6.0) & we have vRealize Log Insight running,
instead of installing Splunk agents in each VM, can we just pipe all logs from vRealize to
Splunk & this would have captured all VMs Windows security.evtx (& UNIXes syslog) events?

Q2:
Are vCenter events (eg: provision new VMs, new vNICs, vMotion events) captured by
vRealize?

Hi,

I check on my Windows 2012 server and see an application called: "Host Agent Configuration". In details properties for product name it says: "Microsoft Azure Site Recovery"

What is that?

Thanks

Best way to install and download two VM's on 2016 Standard Server? Is it install the 180 Server 2016 Server trial then put in the key that came with the Dell PowerEdge operating system? I've had several licensing issues with VM's in the past.

Thanks in advance

I have a windows server 2016 std machine that is a VM and I am running routing and remote access on it as a VPN connection, and also it has a few NICs in it to go back and forth between 2 subnets. I have a file share on it and have noticed that I cannot move files across the network while RAS is on. Or at least it's not working well at all as it took several minutes to transfer a 24k file as a test. When I disable the RAS service the files transfer at normal speeds. Any suggestions?

Acronis Data Cloud 7.8 Enhances Cyber Protection

A closer look at five essential enhancements that benefit end-users and help MSPs take their cloud data protection business further.

I have a two node plus witness cluster set up in VMware 6.7. The system is currently failed over to one host due to a bad vSAN network card in the other.

While waiting for the HW vendor to ship me a new card, I had to add another VM. It worked, but when I try to power the VM on, I get:

"No host is compatible with the virtual machine."

I assume it has something to do with the failover state? Is there any way to override whatever is causing the error and get the machine started? I don't think it's a real resource issue since there is plenty of memory and CPU available, but I switch the new VM down to 1 CPU and 512MB RAM just in case and it didn't help.

This environment is not in production, but I don't want to risk the other VMs not coming back if they shut down because other still need to test them.

I have build up a new VM with WSUS role on Windows 2012 (Old WSUS server was on 2008).
On the new server under Administrative Console for WSUS its not showing any computers.
I have named the new server the same as old server, what do i have to do to start seeing computers under WSUS?
All computers are pointing to new server on group policy.

Thanks

Have taken the time to update XenServer 6, trying to get it all the way. The most update, however looks to have broken it. This is a super critical machine and I've been on it for 6 hours now.

XenCenter 6.5 cannot see/connect to the host.

The Host seems to be stuck in maintenance mode. When I try to exist maintenance mode from xsconsole, I get ("'NoneType' object has no attribute 'xenapi'",)

The host is pingable and can ping out.

I cannot run any xe commands, it returns: Error: Connection refused (calling connect ).

If you anyone can get me out of this tight spot I will be eternally grateful!

On a Win 7 virtual desktop from Horizon 7.0.3 I get 3 different Windows backgrounds / wall paper.

When logging into a linked clone desktop in a floating pool:
- as a test domain user (which has local admin privileges), I get a black background/wallpaper. I am able to change it but the wallpaper stays black. I can see icons and everything else seems to work.
- as my account (domain admin), I get the typical Win7 Harmony background/wallpaper. I can change it but it still displays Harmony even though in control panel it shows the wallpaper I have selected is active.
- as a local user, I get the Harmony background but can change it to any wallpaper (including Aero themes and slideshows) without issue and is properly displayed.

There is one GPO set on the OU. It is here Windows Components/Remote Desktop Services/Remote Desktop Session Host/Remote Session Environment and the policy "Use the hardware default graphics adapter for all Remote Desktop Services sessions" is set to Enabled. Not sure if this is an issue, especially with the wallpaper correctly displaying in some instances but wanted to mention it.

Further, this golden image has all updates and is up to SP1 so the search results I found regarding the update and a certain hotfix do not apply in this situation. It is not the "black screen" issue that seems to have been prevalent years back.

Any ideas on why the wallpaper will not properly display are welcomed. This is preventing me form rolling this pool out…

We have a client with one physical server running four virtual servers.

This morning all users workstations froze and the virtual servers became disconnected. We can see that they didn't shut down at any point. All servers went off within around 10mins of each other and a further 10mins to all come back on and users working again.

We'd like to know what may have caused this?

Below are what I can see in event viewer around the time this happened:
SQL (Virtual) - The processing of Group Policy failed.  - 10:52:39
Server - The WinHTTP Web Proxy Auto-Discovery Service service entered the stopped state. - 11:01:15
Exchange (virtual) - Warning - A process serving application pool 'MSExchangeServicesAppPool' failed to respond to a ping. The process id was '5416'. - 11:01:51
RDS (Virtual) - A process serving application pool 'DefaultAppPool' failed to respond to a ping. The process id was '4508' - 11:09:27
File (Virtual) - No errors

Any further information needed, just let me know.

We used to label servers with make and model in the old days since they were physical.
We have almost all servers are VMs nowadays .
How do we describe the servers make and model when the vm runs on Hyper-v or Esxi?

Hi

We have Fujitsu Primergy RX200S7 server and the company who did the server consoladitation went into administration.

So sure what is the default password, i tried user name and password as admin.

It is not taking the password:

Please post me tutorials to reset the password. Is this risky procedure?

Any help will be mush appreciated.

Many Thanks

Hey all,

I have just taken over a site and one of the critical servers (VM1) is running out of disk space on the C:Drive. Host is running Hyper-V with plenty of space for allocating extra stroage to VM1. The weird thing is that when I look the Disk management within the VM, it shows that there is space that hasn't been allocated. It also has a replica of free unallocated space on the D:Drive which is very odd.

I would ideally  like to just expand the C:Drive - is this safe to do so knowing I have good backups also?

https://www.cloudcomputing-news.net/news/2016/oct/31/agentless-vs-agent-based-architectures-why-does-it-matter/
https://aws.amazon.com/marketplace/pp/B01LXMNGHB?qid=1541553180900&sr=0-1&ref_=srh_res_product_title

Extracted from above links, "Agentless services, on the other hand, talk directly to the underlying cloud platform (e.g., AWS, Azure)...",

Q1:
Is AWS' AV subscription now an agentless AV?  Is this the agentless Deep Security?

Q2:
If there are appliance VMs (eg: highly stripped-down Linux), is it the way to go to
adopt agentless (as we may subscribe to say Commzgate SMS or cloud-based
services) AV/end-point IPS as agents can't run/install in the stripped-down guest
OS?

Q3:
in the case of AWS' AV/IPS service (ie the 2nd link above), is this an SaaS of FaaS
(Function as a Service)?

Hi,

I have a Veeam VM I used to back up my production host VMs with, as well as replication to a DR box.  I increased the size of the drive for the backups, then realized I need to increase the size of another drive.  vSphere threw an error: 'Cannot complete operation due to concurrent modification by another operation'.

There are no other concurrent operations active on this host, much less VM.   I also looked at the disk management in the VM and it sees the additional space allocated to the first drive.  Oddly though, the 'expand the partition' option is grayed out.

I'm on vSphere 6.7 using vCenter web client.

Thanks!

We are moving some of our apps/systems to the cloud.
However, some vendors for the cloud projects came back to
say that the OS is a stripped down Linux which is hardened
& that it's not applicable to install/run AV.

In view of high profile attacks and audit requirements, I
loathe to raise exemption/deviation even if the cloud VM
is not accessible to public (ie firewalled to our corporate
only).  I noticed that AWS & another vendor that uses VM
on WIndows guest offers AV

Q1:
Is there a quick/easy way for me to verify that the 'strip-
down Linux OS' the vendor uses in the cloud truly could
not support AV?  Guess by running 'uname -a' is not
enough.  Or is there a script for me to verify?
Or can I verify by checking what are the past patches
they had been applying?  If it's all RedHat/Rhel patches
then, it's just simply a hardened RHEL which should
support many AV

Q2:
What are the usual audit requirements for AV for a custom
Linux VM in the cloud?  Don't really need an AV under what
criteria?

Q3:
If it's truly a stripped-down Linux say based on CentOS or
FreeBSD, can I assess the patch requirements based on
CentOS & FreeBSD?  I recall when running a VA scan
against a PABX that's based on RHEL, all vulnerabilities
for RHEL are applicable & the PABX vendor produces
the patches though they are behind RedHat by a few
months in coming out with the patches.

This reminds me of IOT, many of which are appliances
that customizes their OS from …

I have a problem with my VMS .THEY ALL RUN ON ESXI 5.5  .when I copy files between VMs it is very slow not more than 10mb but if i copy the same files between vm and physical it reach 87mb .
I tryed to copy between to VMs they are in the same vswitch and sharing the same port group but I still get the same slow speed.both network configured with E1000.all VMs run windows servers (2003,2008,2016)
