QEMU/KVM-or-HVF crash in installer
Posted: Wed Apr 19, 2023 2:59 am
On both a MacBook Air Intel and an HP EliteDesk 800 G2 Mini (cpus respectively "Intel(R) Core(TM) i5-8210Y CPU @ 1.60GHz" and "Intel(R) Core(TM) i5-6500T CPU @ 2.50GHz") I get similar crashes. I set NODUMP so that the machine doesn't just restart when it crashes, but the virtual disks have not been initialized yet.
The installer loads the ISO into RAM and then there are a bunch of MMG$PAGEFAULT IPLHI.
The weird thing is, I have no idea why it would be page faulting. There's no backing store to page to yet in any event, and it happens with both 8G and 15G defined to the virtual machine.
Anyone got any ideas of what to try?
this is the top...
...and this is the bottom. There are hundreds of lines in between the two, all similar-looking.
