So, I'm trying to track down an ODD issue with Alma 9.
I have a Win2016 .qcow2 system image, 4 core, 8 GB RAM I'm trying to move from one host to the other. Both are running Alma 9, with all updates applied. Both have been configured with similar/identical software. ZFS is the file store in both cases.
The Windows VM starts and works fine on one but not the other. But why? Both are running fresh installs of Alma 9 from the same installation disk.
System 1 "Delta" Xeon 2620 Blade server 128 GB RAM OpenZFS RAIDZ1 on 3x 500 GB SATA SSDs Alma 9 X86/64 Running numerous Virtual Machines Windows Server 2016 runs great
System 2 "Grumman" I7 4790 16 GB RAM OpenZFS RAIDZ1 on 3x 250 GB SATA SSDs Alma 9 X86/64 Runs only 1 Virtual Machine Windows Server 2016 boots to "black screen of death"
During the "black screen of death", top shows 4 cores running at 100% CPU forever. I've tried the 3x power off to trigger recovery mode and that, too, resulted in the same result.
There is nothing in the Grumman's system log. Grumman's CPU is a bit older, but a 2620 is also pretty old.
Any idea where I could look for resolution?
