Red Hat Red Hat has updated its virtualization platform, Red Hat Enterprise Virtualization, to include support for desktop virtualization. The beta version of REV 2.2 will include a number of new programs that will allows customers to run a virtualized desktop infrastructure.

Well isn't that just fantastic.

KVM itself is heavily underrated. It's certainly on par with ESX or Xen, but it has the advantage that support is bundled with pretty much every Linux distribution currently out there by default. It's very fast...

The disadvantages are that the management tools are not as nice, desktop integration is poor, and it requires hardware support for virtualization.

Glad to see Redhat is fixing those issues.

I do use KVM, but it seems to be behind in I/O performance (even with virtio). On my system, Hyper-V, ESXi, and Xen outperform KVM in guest disk performance (with Windows or Linux guests).

For Xen and KVM the disk configuration was the same - LVM volumes stored on RAID or passthrough to a SATA disk. For Hyper-V, the disks were VHD files on NTFS on RAID or passthrough to a SATA disk. For ESXi, the disks were LVM volumes served over iSCSI and used for direct passthrough or VMFS, or passthrough to a SATA disk.

It is entirely possible that there are issues with my KVM configuration causing poor performance over the others, but if so, I haven't seen any obvious causes or documented fixes. I haven't seen any options in virt-manager that might affect performance, either (other than the disk interface - scsi/ide/virtio/etc).

I didn't read anything in the article saying they would remove the requirement for hardware support of virtualization. That seems like it would be more difficult than just providing a nice gui interface and desktop integration.

Not exactly a major limitation these days... that hardware support has been present on all Intel and AMD CPUs for a few years now...

not so for intel chips. some of them have it, some don't. and sometimes, it isn't even possible to tell if a chip has it til you buy it.

on par with ESX?!

Gimme a break... KVM is 10 years behind ESX! vMotion, Storage vMotion, DRS, HA... How can I do something similar with KVM? KVM isn't on par even with Virtual Box!

Well, you keep using your VMware then. With all the packages you just listed, you will end up spending more for the software than you do for the hardware. KVM is moving very fast and the real missing pieces are the smooth management interfaces. Most of the functionality is already there though. Not to mention that RHEV will run ANY hypervisor, KVM, ESX, and VirtualBox. Can your expensive VMware do that? VMware can't even keep their products updated for the latest RHEL release.

You just have no clue do you? Maybe if you knew what was happenning behind those fancy Vmware brand-name features you'd would not be so incredulous.

Yeap. Just keep spending your company's money. I'll just keep doing more with LInux-KVM and spend my company's money on a new laptop for myself.
