XCP: update dom0 kernel?

XCP: update dom0 kernel?

[YAMAMOTO Takashi]

hi,

i want to use linux md driver in xcp's dom0.
however, unfortunately the kernel shipped with xcp build20719 seems to
have a known deadlock bug and unusable for my purpose.

in git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git,
the bug was introduced by:
	449aad3e25358812c43afc60918c5ad3819488e7
and fixed by:
	c8c00a6915a2e3d10416e8bdd3138429beb96210

any chance for it to be fixed for xcp soon?

Thanks for the pointer -- it can definitely be fixed in the next update.

One of the things we want to discuss at the summit next week is the schedule with which we should be aiming to release new XCP install ISOs.

Thanks,
Ian

We're aiming to refresh the XCP install isos by the beginning of June.

Also in the short term I think it would be good to:
1. create an online repo for the storage plug-in scripts
2. automatically build and upload 'unstable' binary snapshots from cron
3. put the 'vhdd' prototype (storage daemon which Jon Ludlam talked about at summit) repo online somewhere

In the medium term I think we should:
1. move stuff like xapi into RPMs for uniformity
2. make a script to rebuild a full install iso from a set of RPMs

There's probably a bunch of other useful stuff we should do. Perhaps we should make a wiki page with a to-do list on it?

Cheers,
Dave

This sounds good. Makes things a lot easier for everyone, including you, I assume :)

xcp 0.2 (RE: XCP: update dom0 kernel?)

[YAMAMOTO Takashi]

hi,

>> One of the things we want to discuss at the summit next week is the schedule with which we should be aiming to release new XCP install ISOs.

one of my coworkers who attended the summit told me
that you said that xcp 0.2 was already available somewhere.
is it right?  if so, where?  i tried google but no luck.

0.1.1 is the current release. The plan is to get a new release out in June.

We can all discuss the longer term roadmap on the planned XCP calls Stephen is arranging.

Best,
Ian

i heard that the next release will use the same kernel and thus will
have the bug intact.  it's a bit disappointing.  is it true?

XCP 0.5 will use the same 2.6.27 kernel as earlier versions, but bug fixes such as this will certainly be backported to it.

I can confirm that the above fix is already in the tree which will be
used for the 0.5 release.
