reboot for paravirt-guests not working in 3.0.4-rc2

[Patrick Scharrenberg]

Hi!

with 3.0.4-rc2 I can't restart domains. Neither with xm nor from within
the domain.

It seems that on a reboot xen tries to run pygrub, which I haven't
configured.

Here the different xend.logs for XendDomainInfo.create on xm create and
xm reboot:


xm create:

xm reboot:

I can confirm reboot doesn't work either by issuing "reboot" from domU
or "shutdown -R" from dom0

Yes, haven't got around to implementing that yet.  Should be
straightforward.

Sorry, I'm referring to paravirt-ops guest Linux kernels; I don't know
about other (xen-unstable based) guest kernels.

Sorry about that.  This is fixed in xen-unstable changeset 13077:d7150286ca7b.

Will the fix be included in the next 3.0.4 RC?

Thank you,
