[Xen-users] Problem with dump-core after restoring machine

[Dawid <murkys@xxxxxxxxx>]

Hello, I have problem with dumping core of hvm domain. Problem occurs
only after previously restoring machine from a save file. There is no
problem with dumping core after creating domain from a scratch and then
trying to dump. Also there is no such problem with paravirtualized domains.

Error message I got (tried using both xm and xl):

xc: error: Failed to write buffer (14 = Bad address): Internal error
libxl: error: libxl.c:479:libxl_domain_core_dump core dumping domain 14
to ./dump.2: Bad address
core dump failed (rc=-3)

and using xm:

Fault 2: "Failed to dump core: (1, 'Internal error', 'Failed to write
buffer (14 = Bad address)')"


My dom0 is Debian Squeeze with Xen 4.1 and kernel 3.0, but also tried
with Xen 4.0 and 2.6.32 kernel. HVM domain is Windows XP (tried 32 and
64 bit).

I'd like to know if this is more general problem (and this is how it
looks for me) or it's just some problem with configuration of my
machine. Does anyone else noticed it? Or could someone check? I
appreciate any help.

Regards,
Dawid O.
