Xen PVM: Strange lockups when running PostgreSQL load
I am currently looking at a bug report[1] which is happening when
a Xen PVM guest with multiple VCPUs is running a high IO database
load (a test script is available in the bug report).
In experimenting it seems that this happens (or is getting more
likely) when the number of VCPUs is 8 or higher (though I have
not tried 6, only 2 and 4), having autogroup enabled seems to
make it more likely, too

pdb missing files?
Hello,
I''m trying to get PDB working in accordance with the instructions at
http://www.cl.cam.ac.uk/~sos22/replay.bk/docs/misc/XenDebugger-HOWTO and
a message from this list:
http://lists.xensource.com/archives/html/xen-devel/2004-08/msg00017.html
When I try to build pdb I first get errors because the Makefile is
configured to treat warnings as errors, and there are some warnings.

[PATCH 0 of 2] v2: memshare/xenpaging/xen-access fixes for xen-unstable
The following two patches allow the parallel use of memsharing, xenpaging and
xen-access by using an independent ring buffer for each feature.
Please review.
v2:
- update mem_event_check_ring arguments, check domain rather than domain_id
- check ring_full first because its value was just evaluated
- check if ring buffer is initialized before calling

There has been some progress, but still no joy. Definitely not intended for

Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table

Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit

Hongkaixing, I incorporated your suggestion in patch 2, so I should add your

tools: specify datadir for qemu-xen build to fix firmware loading
qemu-xen does currently not find the firmware files, such as
vgabios-cirrus.bin. The reason is that qemu-xen uses the default prefix
/usr/local.

[PATCH] Staging: hv: storvsc: Show the modulename in /sys/class/scsi_host/*/proc_name
mkinitrd relies on /sys/class/scsi_host/*/proc_name instead of
/sys/block/sd*/device/../../../moalias to get the scsi driver module
name.
As a fallback the sysfs driver name could be used, which does not match
the module name either ('storvsc' vs. 'hv_storvsc').
