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.
