Hi all,
I've just spent a bit more time testing my system. Simply doing the
following results in a boot hang:
# pkg install driver/i86pc/kvm
# reboot
If I make a zfs snapshot right before doing that, I can boot from
another BE in the grub menu, rollback to the snapshot and then boot in
my main BE.
If I disable all virtualisation features in my board's bios, then I
get a kernel panic, which was recorded to a zvol: rpool/dump (which is
nearly 8GB in size). With Virtualisation enabled, then it's the silent
hang.
It's quite odd that if I install KVM fully, it loads at install time
and I can use it, but no luck rebooting later.
Has anyone else seen this sort of problem with KVM?

Hi all,
I've installed oi-151 on a new machine recently, and it's running
great, but it will not reboot. I've made some boot environment clones
as I've gone along and I can always roll back to the clean install,
and that will boot, but it seems that after I install kvm and a few
other bits (apache, mysql, etc), it doesn't want to reboot.
The hardware is an Intel S1200BTL motherboard with a Xeon E3-1230
processor with 16GB RAM.
I've been through this process a number of times now, rolling back,
reinstalling, yes it works, reboot = hang. The hang is an odd one, it
happens very late in the boot process, when the graphical login appears.
If I disable the graphical console and splashscreen and add some
verbose logging to the grub boot command, I can see services loading
up, and as the network comes online I can ping the machine successfully.
The last text I saw on the screen before was this:
pseudo: pseudo-device: kvm0
genunix: kvm0 is pseudo/kvm0
A few seconds after this the screen blanks - I assume this is where
the graphical login would normally appear - and then the machine
totally stops responding to network pings, keyboard events, etc. The
capslock light on the keyboard won't toggle (is that a bad sign?).
kvm being the last thing logged could be a coincidence... it's just
the last thing in the log before the screen blanks.
Does anyone have any ideas as to how to track this down?
Thanks,
Matt
