Is your swap device ZFS backed like a ZVOL or something?
Hi Adam,
The hypervisor does indeed have swap on zfs. I will try disabling
swap in the guest. I am pretty sure the panic was due to the guest
hitting and stalling on swap inside the VM. The guest dmesg is attached.
There does not seem to be much memory pressure on the hypervisor. The
hypervisor disk is a little slow, as I am experimenting with hast to
sync across to another zfs box. However, thats only for a zfs volume
that holds the VM disk images. The OS is not "hastified"
In the hypervisor
# pstat -T

The machine has 16G. Should I think of limiting ARC ?
