similar to: Modifying xc_save and xc_restore

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

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

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) : ---- [2008-03-03 10:12:52 15205] INFO

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.

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as

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

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

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.
