[CentOS-virt] virtio

[Kanwar Ranbir Sandhu]

Hello Everyone,

Can I use virtio modules for network and block devices in CentOS 5.3 VMs
when using the KVM packages from the lfarkas repo?  I've tried change
an existing VM to virtio for disk and network, but each time I start it,
I get this error:

error: Failed to start domain popdns02
error: internal error unsupported disk type 'vda'

I don't know why this is happening.  From what I've read, virtio should
be available.  Can someone please tell me what I'm doing wrong?

Regards,

Ranbir

[CentOS-virt] Performance tunning CentOS / Xen

[Ryan Chan]

Hello,

I have followed standard documents to install CentOS 5.3  Xen.
After playing around, stuffs are OK.

So I move forward to tune the performance, are there any recommended
documents/tutorial that specialized on performance tuning VM
host/guest, on CentOS / Xen architecture?

Thanks
