I''m having issues with HVM live migration and every xen version I''ve tried - 3.0.1, 3.1.x, 3.3.0 and 3.3.1. Migrations will fail intermittently with messages like this on the receiving hypervisor: [2009-02-02 11:35:19 12629] DEBUG (XendCheckpoint:264) [xc_restore]: /usr/lib64/xen/bin/xc_restore 4 4 2 3 1 1 1 [2009-02-02 11:35:19 12629] INFO (XendCheckpoint:403)

Hi guys I have few problems with live migration ... and I need some professional help :) I have 2 xen servers ...

I have several systems running 64bit SLES11SP1. I''m trying to Live Migrate between a couple of them and it''s not working, although the same VM will run on each one starting it manually. The system are not identical. Would one expect migration to work between these two systems? See below. Thanks, James The first system is a ProLiant DL360 G6: Proc 1:2533 MHz Execution

Hi, i do some tests with restoring HVM winxp-domU''s. Even, if i restore a saved DomU from a ramdisk, the Restoring-process has only a bandwidth about 23MB/sec: Here a example restoring an 512MB HVM opensuse10.3 DomU ......

Hi all, I am using Xen 4.0.0 on top of Ubuntu Lucid (amd64), with the Jeremy kernel taken from git (xen/stable-2.6.32.x branch, 2.6.32.12 when I am writing this email). This kernel is also used in my domu. I can save a domu without any problem, but restoring it may need from 2 to 5 minutes, from a 1G checkpoint file (domu has 1GB RAM). There also errors in /var/log/xen/xend.log :

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

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.

I am now testing XEN live migration on two physical hosts with XEN 4.0.1 pvops Ubuntu 10.10 (2.6.35-22). Host A also acts as a NFS server, and Host B acts as a NFS client. When I migrate a guest domain from B to A. The ssh connection experiences a downtime of about 1 minute (the terminal does not react to the keyboard input till about 1 minute later). However, the "sudo xm console" does

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

Hello, When I snapshot a vm( hvm centos ) the first time, it succeed. There is a snapshot file on disk and the vm is running. But when I do it the second time, it fail for timeout. what''s wrong with it? This error happened when I used xen-4.0.1-rc5 and kernel-2.6.31.13. Today I update to xen-4.0.1 and kernel-2.6.32.25, it is with the same wrong. Error message:

I got latest (13601) yesterday evening. This doesn''t seem to work to do Restore (at least of the Windows test-image that I''ve been using for testing previously). The VM restores reasonably OK, but it jumps to an invalid address shortly after restoring, giving a D1 blue-screen error (DRIVER_IRQL_LESS_OR_EQUAL), which turns out to be "page-fault in driver" after I

Hi, I have three Xen hosts running Xen 4.0.2 (OpenSuSE 11.4 based). I also have one ''NFS'' server with an NFS export holding VM images and configuration files. Each host has a dedicated LAN link directly to the NFS server. I have another separated NFS export for VM locking (but I had the same issues before). When I attempt to live migrate a VM, it *looks''*like

Hi folks, we (the company i am working for) are running several dozens of virtualisation servers using CentOS 6 + Xen4CentOS as the virtualisation infrastructure. With the latest versions of all packages installed [1], we see failures in live-migration of stock-CentOS6 HVM guests, leaving a "Domain-unnamed" on the source host, while the migrated guest runs fine on the target host.
