Believe me, I have already been through all this. The Pentium 4 does not have hardware virtualization. > what parts of it don't work? I already explained this. On the Pentium 4, which does not have hardware virtualization, KVM is so slow that it is unusable (it takes 10 minutes to boot a Windows XP VM). Therefore I use VirtualBox instead. On the Core Duo at work, which does have hardware virtualization, KVM performance is good, but the VM crashes as soon as I access it in the morning if it is left idle overnight, and I have to reboot the VM. This is fine for a Windows XP VM that I use just so that I can run a couple of required proprietary applications at work; usually I remember to hibernate it before I go home, and it restores just fine. So I continue to use KVM on my work desktop. But this would not be acceptable in high availability situations, so I use Xen to run production VM servers. --Greg -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
