Re: [xen-discuss] Solaris10 10/08 domU crashes host

Chris;

UFS for the root disk within the HVM (domU) but ZFS for the root disk for the underlying base system i.e. dom0.

The HVM was actually residing on a ZFS allocated device i.e. /dev/zvol/dsk/rpool/sol10'.

It seemed to me that ZFS is rather memory hungry and I allocated only 1597440 bytes of memory to the HVM. I then decided not to use ZFS for the HVM root.

I'm sure ZFS folks will disagree with my statement on ZFS being a memory hungry er.... feature. :)

Warmest Regards
Steven Sim

the S10u6 guest with UFS on the zvol.
    

I'm up and running with S10u6 as an HVM guest, although I had to install the guest using UFS.  Installing the guest to a ZFS root when using a zvol from the dom0 will still crash the host.  Just out of curiosity Steven, did you install your guest using UFS or ZFS?  Thanks
