I seem to have some issues getting the Solaris 11.4 ISO to boot, which I think are unrelated to the MSR changes. I get what seems to be a panic just after the Copyright message, but there's no reason printed at all about the panic. The message just reads (transcript): SunOS Release 5.11 Version 11.4.0.15.0 64-bit Copyright (c) 1983, 2018, Oracle and/or it's affiliates. All right reserved. System would not fast reboot because: newkernel not valid fastreboot_onpanic is not set ... The config file I'm using is: memory=1024 vcpus=4 name="solaris" builder="hvm" disk = [ 'format=raw,vdev=hdc,access=ro,devtype=cdrom,target=/root/sol-11_4-text-x86.iso', 'format=raw,vdev=hda,access=rw,target=/root/solaris.img', ] vif = [ 'mac=00:16:3E:74:3d:88,bridge=bridge0', ] vnc=1 vnclisten="0.0.0.0" serial='pty' on_crash="preserve" Is there anything I'm missing? Thanks, Roger.
