Hello,
I have this problem I posted for beta4 also with the RC1 installation:
https://lists.ovirt.org/archives/list/users@ovirt.org/message/CR6XYIEYHT4...
At final stage when engine VM has to start from hosted engine storage domain
libvirt.libvirtError: unsupported configuration: unknown CPU feature:
tsx-ctrl
2020-05-08 17:13:51,080+0200 INFO (vm/7194f9ff) [virt.vm]
(vmId='7194f9ff-1d73-4a0d-987e-3e82060c2d99') Changed state to Down:
unsupported configuration: unknown CPU feature: tsx-ctrl (code=1) (vm:1629)
any hint on how to workaround and test on my nested environment?
Thanks,
Gianluca

+Ryan Barry <rbarry(a)redhat.com> +Michal Skrivanek <mskrivan(a)redhat.com> can
you please look into this? Seems like in 4.3.9 CPU was set to
-machine pc-i440fx-rhel7.6.0,accel=kvm,usb=off,dump-guest-core=off \
-cpu Skylake-Server,spec-ctrl=on,ssbd=on,md-clear=on \
while on 4.4.0 it's set to:
<cpu match="exact"> <model>Cascadelake-Server</model>
<feature
name="md-clear" policy="require"/> <feature
name="mds-no"
policy="require"/> <feature name="hle"
policy="disable"/> <feature
name="rtm" policy="disable"/> <feature name="tsx-ctrl"
policy="require"/>
<feature name="arch-capabilities" policy="require"/>
<topology cores="2"
sockets="16" threads="1"/> <numa> <cell
cpus="0-31" id="0"
memory="16777216"/> </numa> </cpu>
and it fails on missing tsx-ctrl feature.
Maybe related to partial implementation on *Bug 1674420*
<https://bugzilla.redhat.com/show_bug.cgi?id=1674420> - [RFE] - add support
for Cascadelake-Server CPUs (and IvyBridge)
which is targeted to 4.4.2?
Gianluca, can you confirm your host has Cascadelake-Server CPU ?
If so, please note Cascadelake is not listed in supported CPUs:

Thanks,
Gianluca

I confirm that in vdsm.log of the nested host in RC1 I see this config for
the engine vm:

Gianluca, can you confirm your host has Cascadelake-Server CPU ?
The physical host cpu is detected as:
model name : Intel(R) Xeon(R) Platinum 8260L CPU @ 2.40GHz
and its cpu flags:
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat
pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb

dtherm ida arat pln pts hwp hwp_act_window hwp_epp hwp_pkg_req pku ospke
avx512_vnni md_clear spec_ctrl intel_stibp flush_l1d arch_capabilities
The physical host itself is a 4.3.9 single host HCI system and during
install (made with 4.3.8) has been setup as "Intel Skylake Server IBRS SSBD
MDS Family" type cluster
I confirm that both in physical 4.3.9 and in another nested 4.3.9 enf I set
up, the related HostedEngine VM is started with:
-machine pc-i440fx-rhel7.6.0,accel=kvm,usb=off,dump-guest-core=off -cpu
Skylake-Server,spec-ctrl=on,ssbd=on,md-clear=on,vmx=on
Gianluca
If so, please note Cascadelake is not listed in supported CPUs:
OK, but strange that I was able to install 4.3.8 without problems....
Is there a way in HCI setup to specify a "lower level" cluster type from
the beginning?
