The main Xen mailing list ("xen-users") generally advises
users to limit the memory on dom0 to 2Gb or less. Apparently the
general version of Xen has troubles with this.
What's the corresponding advice for the Xen in OpenSolaris,
Nevada b87 in particular? I've got an X4600 with 32Gb of physical
memory on it. I was originally planning to have dom0 be the general-
purpose compute instance, and also have it serve a collection of
Linux guests.
Am I better off having a smallish 2Gb OpenSolaris dom0,
a giant OpenSolaris domU for most compute jobs, and a bunch of
smaller Linux domUs for the Linux users?
And if so, for heaven's sake why? What purpose does this
limitation serve?
