Hello

For the past three years I have my computer been set with with multiple 
virtual machine assigned to a GPU using QEMU/KVM and VFIO. For the past 
year CentOS as been the host computer, it has been reliable.  This 
summer I switch to the Centos Enterprise package, it been work for 
several weeks until Friday, sometime over the weekend the console 
portion of the boot process does not display.  I have one Windows 10 
virtual machine book, but the EFI boot screen does not display and the 
Windows circle do not dance on the screen. I am unable able to boot my 
other virtual machines, they get stuck the monitor just flash on and 
off.

I performed a major upgrade on the 4th of July it work through Friday.  
I have used the history command in yum to undo the update the problem 
persisted.  I have qemu-kvm-ev-2.10.0-21.el7_5.4.1.x86_64 and 
libvirt-3.9.0-14.el7_5.6.x86_64.  I can post a configuration if you 
think it will help, I have regenerated a xml file from partially working 
Windows 10 machine. What has changed in the last week. I have tried many 
things but not sure were to go from here.

Thank you
Aaron
