ovirt 4.4 RC1 HCI single host problem unknown CPU feature: tsx-ctrl
Hello, I have this problem I posted for beta4 also with the RC1 installation: https://lists.ovirt.org/archives/list/users@ovirt.org/message/CR6XYIEYHT4N75... 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

any hint on how to workaround and test on my nested environment?
+Ryan Barry <rbarry@redhat.com> +Michal Skrivanek <mskrivan@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: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_usi...

I confirm that in vdsm.log of the nested host in RC1 I see this config for the engine vm: ... <name>HostedEngine</name> <uuid>7194f9ff-1d73-4a0d-987e-3e82060c2d99</uuid> <memory>16777216</memory> <currentMemory>16777216</currentMemory> <iothreads>1</iothreads> <maxMemory slots="16">67108864</maxMemory> <vcpu current="2">32</vcpu> <sysinfo type="smbios"> <system> <entry name="manufacturer">oVirt</entry> <entry name="product">RHEL</entry> <entry name="version">8-1.1911.0.9.el8</entry> <entry name="family">oVirt</entry> <entry name="serial">d584e962-5461-4fa5-affa-db413e17590c</entry> <entry name="uuid">7194f9ff-1d73-4a0d-987e-3e82060c2d99</entry> </system> </sysinfo> <clock adjustment="0" offset="variable"> <timer name="rtc" tickpolicy="catchup"/> <timer name="pit" tickpolicy="delay"/> <timer name="hpet" present="no"/> </clock> <features> <acpi/> </features> <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> ... <os> <type arch="x86_64" machine="pc-q35-rhel8.1.0">hvm</type> <smbios mode="sysinfo"/> <bios useserial="yes"/> </os> ...

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? Gianluca
