Modifying Xen migration
Hello everyone,
for research purposes I''m working on Xen 3.0.3 and trying to make some
modifications to Xen migration. By looking at the documentation, I''ve
learned that the part I''m interesting in are handled by two binaries
(xc_save and xc_restore), so I thought about modifying just this two
binaries instead of recompiling the whole Xen everytime, so what I do
is just

Migration stalls with 2.6.26.5 kernel
Hello,
I have been struggling through the task of moving our infrastructure
over to Xen VMs. We were initially using Ubuntu packages for both dom0
and our domUs, but experienced extreme instability so we moved to
CentOS, which has been much more reliable for dom0. Since we already
had a bunch of Ubuntu VMs, we left them using the Ubuntu 2.4.24-19-xen
kernel, but this has turned out to be

Live migration problem with xen 3.2
Hi,
Live migration was working well for me with 3.1.
Recently I move to 3.2, and now live migration does not work anymore.
Here is what i obtain on source node :
----
xm migrate --live webdav node2
Error: /usr/lib/xen-3.2-1/bin/xc_save 26 6 0 0 1 failed
Usage: xm migrate <Domain> <Host>
[...]
----
And in the xend.log (still on the source node) :

where is tools\xcutils\xc_save used?
I want to add some parameters when vm is migrated. As I can see , vmm will
use xc_domain_save(tools\libxc\Xc_domain_save.c) function ,and the main
function of xc_save.c is responsible for inputting parameters.
so I just want to know which function will use this executable file.
Thanks

Live migration fails depending on on the kernel Version of DomU
Hi,
I''m running a two node xen-Cluster with CentOS 5.3. I''m using
gfs2 for the cluster filesystem and kernel 2.6.18-128.1.6.el5xen #1 SMP
for Dom0 (xen 3.0.3).
Live migration works fine as long as the DomU guest is running CentOS 5.3
or SLC 4.7 with kernel version 2.6.9-55.EL.cern. But if the SLC 4.7
guest is
running the current 2.6.9-78.0.17.EL.cern kernel, the migration

tools: do not link against unused libraries.
A fair few things under tools link against libraries which they don''t
even use.
Most of this appears to come from copy-and-pasting previous Makefile

soft lockups during live migrate..
Trying to migrate a 64bit PV guest with 64GB running medium to heavy load
on xen 3.4.0, it is showing lot of soft lockups. The softlockups are
causing dom0 reboot by the cluster FS. The hardware has 256GB and 32
CPUs.
Looking into the hypervisor thru kdb, I see one cpu in sh_resync_all()
while all other 31 appear spinning on the shadow_lock. I vaguely remember
seeing some thread on this while

Internal error during live migration saving
Just wondering if this is a known bug?
Trying to migrate the VM off to a diff dom0 results in the below error.
Other VMs migrated off fine (started at around the same time as this vm)
and I''ve tried a few different target servers, all resulting in the same
thing.
