[Xen-devel] tapdisk2 segfaults with xen-unstable+linux-2.6-pvops

[Ashish Bijlani <ashish.bijlani@xxxxxxxxx>]

Hi,

I'm trying to run guest pv vm on my machine running xen-unstable
(xen-4.0.0-rc3.pre + linux-2.6-pvops). However, I get blktap error:

"
sudo xm create -c xmexample
Using config file "./xmexample".
Error: Failed to create device.
    stdout: unrecognized child response
    stderr:
Check that target "/home/ashish/xen/hd.img" exists and that blktap2
driver installed in dom0.
"

Dom0 dmesg shows:

"
[ 7112.648271] blktap_sysfs_create: adding attributes for dev eb5506c0
[ 7112.648287] blktap_control_allocate_tap: allocated tap de87e000
[ 7112.651564] tapdisk2[7325]: segfault at 10 ip b763a540 sp bffd548c
error 4 in libpthread-2.7.so[b7633000+14000]
"

tapdisk2 -n aio:/home/ashish/xen/hd.img output shows the same above segfault msg

Any ideas what could be wrong?

config, xmexample, and dmesg attached.

Thanks,
Ashish
