I think there was a bug discussed on the list.

Below are the steps we followed - Exported an OVF of a plain windows vm from vmware. - Imported it as an OVA to OLVM - Start the VM after change OS type to Windows 2016. As soon as we select Windows 2016 the server doesnt start but works when we make it as other OS. We want to automated provisioning and setup of the vm through sysprep but the vm doesnt start once we select OS as Windows on the template or any vm created out of that template. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/VB7UUXUC2O6...

Hello, I work along with Moiz and here's what we tried. We created a blank VM, loaded Windows 2016 ISO and booted it up. When we select the OS as Windows 2016 x64 the ISO is loaded but the screen is stuck with the windows logo. The CPU spikes up to 99%. However if we select the OS as 'Other OS' the installation proceeds. We compared the XML files in both cases and noticed that the below parameters are added when we select the OS as windows 2016. <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <synic state='on'/> <stimer state='on'/> </hyperv> <timer name='hypervclock' present='yes'/> I guess this is expected because of the line "hypervEnabled = vmInfoBuildUtils.isHypervEnabled(vm.getVmOsId(), vm.getCompatibilityVersion());" in https://github.com/oVirt/ovirt-engine/blob/ovirt-engine-4.3/backend/manag... However the question is why are the hyperv enlightenments causing a problem? The host details are as below: Linux server01 3.10.0-1160.49.1.el7.x86_64 #1 SMP Tue Nov 23 11:18:01 PST 2021 x86_64 x86_64 x86_64 GNU/Linux lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 96 On-line CPU(s) list: 0-95 Thread(s) per core: 2 Core(s) per socket: 24 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 85 Model name: Intel(R) Xeon(R) Platinum 8160 CPU @ 2.10GHz Stepping: 4 CPU MHz: 2100.000 BogoMIPS: 4200.00 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 1024K L3 cache: 33792K NUMA node0 CPU(s): 0-23,48-71 NUMA node1 CPU(s): 24-47,72-95 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 rdtscp lm constant_tsc art arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 sdbg fma cx16 xtpr pdcm pcid dca sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm 3dnowprefetch epb cat_l3 cdp_l3 invpcid_single intel_ppin intel_pt ssbd mba ibrs ibpb stibp tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 hle avx2 smep bmi2 erms invpcid rtm cqm mpx rdt_a avx512f avx512dq rdseed adx smap clflushopt clwb avx512cd avx512bw avx512vl xsaveopt xsavec xgetbv1 cqm_llc cqm_occup_llc cqm_mbm_total cqm_mbm_local dtherm ida arat pln pts hwp_epp pku ospke md_clear spec_ctrl intel_stibp flush_l1d The CPU type in ovirt detects it as Intel Skylake-Server-noTSX-IBRS Family.
