Re: [Xen-users] create LVM-based domU using more than one volume group

Is it possible to create a guest installation which sources its
partitions using more than one volume group. For example, let's
saying there are two VGs on dom0, vgxen1 and vgxen2, could I define
the guest creation paramters such that root and swap are LVs within
vgxen1 and home is an LV within vgxen2?
Xen doesn't care - you just need to specify the right block device
for each virtual disk.
Is there an additional flag I can add to xen-create-image maybe?
Ah, now that's a different matter. I don't use tools any more for
creating images - I just manually create block devices and either
copy a template blank guest onto them, or us debootstrap to install a
fresh install (all my hosts and guests are Debian).
Worst case is that you could create the guest using just one (or a
small number of) devices, then once it's installed you can mount the
disks in Dom0 and move stuff about - eg make a new filesystem for
/home, mount it as (say) /mnt2, move everything from /mnt/home/ to
/mnt2/ (assuming the guest root is mounted at /mnt), and then edit
the guest fstab.
