Yep -- please update and reboot. Or try a non-Windows ostype (even if it's
Windows) if the enlightenments are not critical to you, but downtime is
Thanks Ryan,
After kernel updated to 3.10.0-957.10.1.el7.x86_64, Windows can be launch.
The host has vdsm-4.30.9-1.
To make sure CentOS 7.6 has the correct kernel, I was wondering we may
want to fix the vdsm for the following lines:
%if 0%{?rhel}
%if 0%{?centos}
# 7.6 baseline
Requires: kernel >= 3.10.0-957.el7
%else # RHEL
# Required for new hyperv flags for Windows
https://bugzilla.redhat.com/1644693
Requires: kernel >= 3.10.0-957.3.1.el7
%endif
Ok by me. Generally, we expect that users upgrading to 4.3 will also catch
the
latest CentOS updates, but no harm in being safe
