Re: moving from Xen to KVM

What is needed to install kvm? I have the non xen kernel as  the default. I have virsh, virt-install installed. What am I missing in my config? Look at my second bullet point to get a sense of where I am stuck.

Thanks for your help,
Dave

Did you install kvm?

If you need to move the xen virtual machines to kvm you will need to boot them in rescue mode, change your modprobe.conf to load the regular scsci and nic drivers, install a regular kernel, remove the xen console from inittab and remove console=xvc0 from your /etc/grub.conf and reboot.

Hello All,

I have been building a new server to deploy using Xen. However, seeing that Redhat is moving towards KVM, it would seem beneficial to deply this server using KVM as well. This is a Centos 5.4 x86_64 fresh install.

So here is the scoop:
  • running the xen kernel with 2 vms works great. I have 2 vms- a cobbler host and an ldap host.
  • running with non-xen kernel, I can't seem to get anything to work right. Using virt-install from the command line, I get the response of "Host does not support any virtualization options" yet I know it does.

What am I missing here?

I spent some hours last night searching and came up empty.

Thanks in advance,
Dave
