+++ This bug is an upstream to downstream clone. The original bug is: +++ +++ bug 1534212 +++ ====================================================================== Description of problem: I'm opening this bug for both clean install and upgrade, though I assume we'll need to split it later. We need to ensure that: 1. Clean installation on a host with IBRS compatible fixes (CPU + kernel + qemu-kvm + libvirt) can select an IBRS enabled vCPU type for the SHE VM. 2. We need to provide a procedure on upgrade to switch to such CPU type (already doable today?) (Originally by Yaniv Kaul)
The bug is verified on build rhv-4.1.10-5 Steps: 1. installed image from kobler on panther09.qa.lab.tlv.redhat.com. 2. installed repoes of the build rhv-4.1.10-5, yum update -y, reboot 3. echo 2 > /sys/kernel/debug/x86/ibrs_enabled (turn on IBRS in both userspace and kernel (IBRS always)) 4. yum install ovirt-hosted-engine-setup yum install rhvm-appliance hosted-engine --deploy Result: hosted engine installed. While installation the following CPU type was chosen: model_Haswell-noTSX-IBRS. The following CPU types are supported by this host: - model_Haswell-noTSX: Intel Haswell-noTSX Family - model_Haswell-noTSX-IBRS: Intel Haswell-noTSX-IBRS Family - model_SandyBridge: Intel SandyBridge Family - model_SandyBridge-IBRS: Intel SandyBridge-IBRS Family - model_Westmere: Intel Westmere Family - model_Westmere-IBRS: Intel Westmere-IBRS Family - model_Nehalem: Intel Nehalem Family - model_Nehalem-IBRS: Intel Nehalem-IBRS Family - model_Penryn: Intel Penryn Family - model_Conroe: Intel Conroe Family Please specify the CPU type to be used by the VM [model_Haswell-noTSX]: model_Haswell-noTSX-IBRS [ INFO ] Stage: Setup validation --== CONFIGURATION PREVIEW ==-- Bridge interface : em1 Engine FQDN : nsednev-he-6.qa.lab.tlv.redhat.com Bridge name : ovirtmgmt Host address : panther09.qa.lab.tlv.redhat.com SSH daemon port : 22 Firewall manager : iptables Gateway address : 10.35.65.254 Storage Domain type : nfs3 Image size GB : 58 Host ID : 1 Storage connection : yellow-vdsb.qa.lab.tlv.redhat.com:/Compute_NFS/pagranat/he_panther Console type : vnc Memory size MB : 16384 MAC address : 00:16:3e:ee:ee:ee Number of CPUs : 4 OVF archive (for disk boot) : /usr/share/ovirt-engine-appliance/rhvm-appliance-4.1.20180125.0-1.el7.ova Appliance version : 4.1.20180125.0-1.el7 Restart engine VM after engine-setup: True Engine VM timezone : Asia/Jerusalem CPU Type : model_Haswell-noTSX-IBRS ...
