[one-users] virtio setup

[Olivier Sallou]

Hi
I have set up virtio on a Debian recent image (and guest has drivers
loaded) but I face some perf issues (frequent freezes with kernel errors).

I looked at open nebula generated template and I see in deployment file:

        <disk type='file' device='disk'>
            <source file='/var/lib/one//datastores/0/697/disk.0'/>
            <target dev='vda'/>
            <driver name='qemu' type='raw' cache='none'/>
        </disk>

My disk is correctly mounted as vda, but I do not see any "virtio"
reference in the VM template, is it fine ?

In kvm command line I see drive related info:

...  -drive
file=/var/lib/one//datastores/0/697/disk.0,if=none,id=drive-virtio-disk0,boot=on,format=raw,cache=none
-device
virtio-blk-pci,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0

Is configuration ok (and I should investigue somewhere else) or is there
an issue with my config ?

In Image template I have DEV_PREFIX=vd.

I use OpenNebula 4.2.0


Thanks

Olivier
