Re: [Xen-devel] domU does not attach disk under periods of high IO?

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

There was a bug in the kernel xenbus implementation where blkfront would not wait for partition tables to be parsed before signalling that a device connection was ‘ready’. Take a look and see if your blkfront.c in your kernel has a function called ‘blkfront_is_ready’. If not, then you need changesets 82 and 217 from http://xenbits.xensource.com/linux-2.6.18-xen.hg

There have also been problems with a buggy version of nash. I can’t remember the precise details right now unfortunately.

Hi all.  I've noticed issues with domU kernels not attaching to their disk device at bootup under periods of high IO (per my bug report at http://bugs.centos.org/view.php?id=2317  <http://bugs.centos.org/view.php?id=2317> ).  This also occurs under Fedora Core 8 dom0 which is on a build of Xen 3.1.  As I've inquired about this to xen-users with no response, I'm curious if this is a known issue and if/when you guys plan on addressing it.
 
Sincerely,
