Hello, having some environments born before 4.3.0 and Q35 introduction. Now on 4.3.3, but of course existing VMs seem not impacted and retain their machine type, eg a dumpxml gives:
<type arch='x86_64' machine='pc-i440fx-rhel7.6.0'>hvm</type>
the default is still i440fx, so no change is expected unless you change configuration
Any advise if I want to update any of them to Q35 (supposing their installed OS does support that kind of hw emulation, of course)? Apart from shutdown, edit, system, advanced parameters, change, save and boot?
UEFI switch usually requires a reinstall because of the disk layout, but just i440fx-q35 seabiaos switch should indeed work just fine
This question leads me to something strange I have noticed: updating cluster to 4.3, when 4.3.0 was released, seems not to have changed default "Emulated Machine" type for it. In fact if I go in my cluster, I see it still with value "pc-i440fx-rhel7.6.0", even if its compatibility version is 4.3. Is this expected?
yes
If I edit the cluster I don't see an option to change to q35.
eeh, yeah, a cluster-wide setting is still not finished. It will get into 4.3.z. For now you can only change individual VMs.
My cpu type is "Intel Westmere IBRS SSBD Family", could it influence this situation in any way?
no, not at all. Thanks, michal
Thanks in advance,
Gianluca
