CentOS virt - Jul 2020 - Pushing real machines into KVM/Qemu

Hi all,

I took a real Core 2 machine (T7200? whose motherboard was starting to die?)
running Fedora 29 and dd?d the SSD over to my KVM server, then created a VM
using ?create from existing image?.

After some tweaking, including setting the disk type to ?SATA? from ?Virtio?, I
got it working.

Is there a fixed recipe for virtualizing CentOS/Fedora/RHEL instances into
running VM?s on KVM/Qemu?

Like re-running dracut and adding any particular drivers, etc?

It works, but I don?t know how efficient the emulation is.

The host hardware has IGB NIC?s, and I?m using ?hostdev? as the network type, so
that seems to be working well enough with the ?igbvf? driver.

Any tips would be appreciated.

Thanks!

Hi,

never testet by myself:

usage of virt-p2v

That probably would have been useful if I hadn?t waited until the physical
instance?s motherboard started to give out?

I?ll try rebuilding with hostonly=no and adding all the virtio_* drivers I can
find? Anything else I need to virtualize a host?

Thanks
