Subject: Trying to track down odd behavior, errors in xen dmesg
Date: Wed, 6 Apr 2011 11:30:02 -0500	[thread overview]

Hi,

I'm having a strange issue with Xen 4.0.1 AMD64 (debian squeeze).
I am importing a iSCSI lun into dom0 from a storage array (using
open-iscsi), this is used as the disk [phy:] for my domU.
If I use HVM, the install works correctly. As soon as I switch to pv
for the disk drivers (after installing a xen kernel in the domU) I get
a slew of messages in xm dmesg:

(XEN) grant-table.c:1956:d0 Could not get src frame 3f3149
(XEN) printk: 1851 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f3728
(XEN) printk: 1354 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f3485
(XEN) printk: 1890 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f3e58
(XEN) printk: 2153 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f3c9c
(XEN) printk: 1912 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f4287
(XEN) printk: 2287 messages suppressed.
(XEN) grant-table.c:1956:d0 Could not get src frame 3f40dc
Disk speed is very slow as well. Running DD in the domU to write a
file to disk causes more error messages to appear.  It also badly
corrupts the disk in some cases.
Testing from a local LVM works without error in all cases.

Any suggestions?
