similar to: live migration of winodws based domUs

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 there, We are using latest version of XCP on 6 hosts. While issuing VM.start or VM.start_on xmlrpc functional call , it says : {''Status'': ''Failure'', ''ErrorDescription'': [''SESSION_INVALID'', ''OpaqueRef:cfb6df14-387d-40a1-cc27-d5962cba7712'']} However if I put VM.start in a loop maybe after

In trying to compile a package with c code using Rtools, -O3 is added by default. This comes from Makeconf? Compiler flags (CFLAGS="-O0 -g" ) set in src/Makevars.win or src/Makevars appear before this. nm pkg.dll reveals no symbols! How can I compile a Windows package with "-O2 -g"? Thanks, RT -- View this message in context:

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

Hi all, I need to make some modifications to xc_save and xc_restore to Xen 3.0.3 for research purposes. In order to avoid to recompile all the xen source at each modification I do to these binaries, I thougt to substitute the version of this two binaries which is installed in /usr/lib64/xen/bin, with a version I compile myself from the Xen source code tarball. The problem is that after doing

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

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

Dear all: I am trying to migrate a WinXP HVM (64M memory) from a machine (sender) to another machine (receiver) through AoE disk, however, there are some errors when do the following command: (My xen version is xen-4.0.1-rc5.hg, kernel 2.6.31.13, xen xen-4.0.1-rc6-pre, Both sender and receiver are the same xen version) xm migrate --live domain_id receiver_ip

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, 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

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. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

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''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.

Hello, what would be the easiest and fastest way to migrate a file based DomU to a LVM based DomU. Given that the file contains a partition table + partitions. I tried with an dummy approach: dd if=/path/to/file.img of=/dev/volumegroup/logical-volume. That gives me a logical volume that xm create refuses to use....

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 vast majority of the code is in second patch. The first patch merely changes the xenstore key name used by hvmloader to store the buffer address.

Hi, I''ve recently installed xen-3.2.1 on my AMD Sempron(tm) machine. It runs gentoo 2.6.21 as dom0 and cpu frequency scaling works in dom0. But inside a domU, cpu frequency scaling is not working. By checking the boot log in domU I found that domU is unable to load the powernow driver: "powernow-k8: BIOS error - no PSB or ACPI _PSS objects" I wonder if it is possible to have

Hello, On a xenserver with several (39) domUs, we experience problems with the system clock of the domUs. The clock seems to drift away several seconds up to two minutes from the dom0 clock. We do have set independent_wallclock=0. According to the docs (i.e. http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs should use the dom0 clock, but apparently that''s not the case.
