I''ve noticed a few projects aimed at dis-aggregating dom0 (stubdom and Derek Murray''s project to move the domain builder to its own domain). Has anyone tried to host xenstore in a domain other than Dom0? What difficulties might such a project encounter?

There are pending patches for this from Diego Ongaro and Alex Zeffert. Should be in xen-unstable pretty soon now. -- Keir On 11/06/2009 23:07, "Adam McKibben" <adam.mckibben@jhuapl.edu> wrote:> I''ve noticed a few projects aimed at dis-aggregating dom0 (stubdom and > Derek Murray''s project to move the domain builder to its own domain). > > Has anyone tried to host xenstore in a domain other than Dom0? > > What difficulties might such a project encounter? > > > Thanks > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Please note that these xen-unstable patches depend on some minor dom0 kernel patches (*). I updated Diego''s linux-2.6.18-xen.hg patches and posted them to this list. But if you''re using an alternate dom0 kernel you''ll need to forward port these. Regards, Alex (*) The kernel patches provide an ioctl for the xenstore domain builder to create a grant ref and event chan which enables the xenstore domain to access dom0''s xenstore page.

Just to check, your tools patches are backwards compatible with old dom0 kernels when running xenstored in dom0? -- Keir On 15/06/2009 10:06, "Alex Zeffertt" <Alex.Zeffertt@eu.citrix.com> wrote:> Please note that these xen-unstable patches depend on some minor dom0 kernel > patches (*).

Yes. You only need a patched kernel if you uncomment the ''#STUBDOM=yes'' line in /etc/sysconfig/xenstore. By default xenstore stubdoms are not enabled, and you get a dom0 daemon that works equally well with a patched kernel or an unpatched kernel.
