Hi,

I'm thinking of installing a virtual machine on my linux (centos 5.x) box. I'm wondering which virtual machine should I get: virtualbox, parallels, vmware.

2) What's the most efficient?

3) I have my centos server running. Will I be able to run my server with no downtime while running the virtual machine at the same time?

The linux box is I think a black edition AMD 2.0 ghz and 4 GB RAM. So I think it should be sufficient to run both at the same time. Thanks,
Victor

1. VMware Workstation 7.0.1, VMware Player 3.0 (free), Oracle Virtual Box 4.0 (free), Parallel all are very good hypervisors.

VMware Workstation 7.0.1

VMware Player 3.0 for free

Virtualbox 4.0 for free

Parallels 4.0

They are all very similar are all do the same job, VMware Player and Virtualbox are very good.

2. Parallels is the best if you want performance in the virtual machine.

I think it depends if you want to spend any money. If you want free, I would select Virtual Box 4.0, but if you want performance, Parallels is the fatest Hypervisor currently. (in a Type 2 Hypevisor)

You may want to increase the memory, if you can.

I would have to say that Virtualbox might be the wise choice here, unless you need something specific. Performance should run well on them all though.

Hi hanccocka,

How much memory more? You think 4 GB may not be enough?

---

1) Should I download the RHEL 5 for Centos 5.x?

2) It doesn't mention about system requirements for VB. What are the system requirements?

Thanks,
Victor

i would usually state as much memory as possible.

but another 4gb should suffice.

You have enough memory, 4GB is enough for any kind of linux distro,windows xp,server 2003, unless of course you are planning on running Windows server 2008 and up then you would have to consider memory upgrade yes

CentOS is RHEL clone. You can download from the website or install for yum repository as the link in my previous post (which is easier but older version).

CPU with virtualization technology will be better. You AMD 2GHz should has it.
Bigger disk drive if you want to have multiple VM.
4 GB is good enough for 1 or 2 VMs. Of course, the more the better.
