Hello,
I'm trying to update an environment from 4.1.7 to 4.1.9.

 
I don't see errors in vdsm logs of target host, but I do see this in /var/log/messages of target host

Jan 26 12:39:51 ov200 libvirtd: 2018-01-26 11:39:51.179+0000: 2588: error : virCPUx86UpdateLive:2726  : operation failed: guest CPU doesn't match specification: missing features: vmx

Indeed dbatest3 VM has this "vmx=on" flag in qemu-kvm command line on source host, even if I never configured it explicitly...:


Both source and target hosts are CentOS 7.4 on Dell M610 with Bios Version: 6.4.0 and Release Date: 07/18/2013 and with same bios settings.

Under Hosts -> General -> Software subtab

- source (4.1.7) has

OS Version: RHEL - 7 - 4.1708.el7.centos
OS Description: CentOS Linux 7 (Core)
Kernel Version: 3.10.0 - 693.2.2.el7.x86_64

- target (4.1.9) has:

The output of dmidecode command on both hosts is the same, apart bogomips and MHz lines.
