Hi All, Does anybody have this problem when try to migrate DomU : Error: /usr/lib/xen/bin/xc_save 22 6 0 0 0 failed I use xen 4.2.2-pre compiled from sources and my machine is Ubuntu 12.04 Linux with kernel 3.2.0-29-generic. Its working perfectly, even remus with drbd support migration was running successfully before. However today after I kill the remus process with command pkill -USR1 remus

Dear all, I am quite new in this virtualization area. I am want to do some experiment with live migration using xen. However, I got problem since my server didn''t support VTx. I am using Ubuntu desktop 12.04 64 bit with Xen 4.1 Amd64. But when I reload the machine it wont start, since the XEN website its doesn''t matter using Paravirtualization without VTx support I dont know

Dear all, Again, I have some question here and I hope some one have experience how to do it. I have Xen 4.2.1 installed from sources and working with XM toolstack. I will use this xen in order to run Remus high availability with DRBD. Does any one know about openvswitch integration with xm toolstack, since Xen wiki only confirm XCP have natively support openvswitch

I'm trying to implement a virtualization API. I was testing migration with libvirt I got some problems. When I use the following command : *virsh migrate --live --persistent --copy-storage-all vm-clone1 qemu+ssh://server_ip/system* the migration works fine but in the destination host the migrated vm is paused and I can't unpause it and I need to reboot the vm to be able use it in the

Thanks for your answer, 1) In this case i'm not using shared storage, the migration is happening between two non-shared storage with full disk copy 2) I already created the file with same size, and the vm works properly after a restart, my problem that it remains paused and I can't resume it until it's rebooted. 3) I'm using qemu-kvm 1.0 On 24 November 2014 at 10:22, Michal

Hi, I''d like to test the stability of live migration during heavy load of domU. scenario: - both dom0s and domU are running on Debian Sarge. - script on dom0 triggers live-migration to the other dom0 - domU is running I/O tests, e.g. bonnie++ - domUs root- (ext3) and swap fs is stored on two partitions in a san - san is connected using fibre channel cards to both dom0s - san in dom0

Dear all, I have sent this problem earlier but maybe its not detail, here I try to write more detail. I hope anybody can help me to point out the problem. First of all I used Ubuntu 12.04 x64 both for domain0 and domainU with modification to run under xen hypervisor and work with remus. I follow and configured the remus with this notes

Hello, I have the same error, server is auto rebooted during every boot with kernel XEN, HS20 with Debian Wheezy and XEN hang on and AMM managment show same errors described in previous mails. With Debian wheezy wit non-xen kernel boots correcte, it seems that problems is with xen kernel Same Server HS20 with Debian Lenny+ XEN 3.2 or Debian Squeeze+XEN 4.0 working perfect Upgraded to Debian

Hi all, Today I got problem below and my domU become unresponsive and I should restart the pc to make it running properly again. [ 240.172092] INFO: task kworker/u:0:5 blocked for more than 120 seconds. [ 240.172110] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

Please tell me if I am wrong : Xen needs LVM to perform domU snapshots and snapshots must be performed by dom0. By the way, a LVM volume group should not be used by more that one kernel at the same time. So if we use a SAN storage, one volume group should be activated on only one server and deactivated on the others. But if we do that, it should not be possible to perform live migration of

I had this exact same problem with 2.0.7. I had done a little investigation and found scheduled_work gets called to schedule the shutdown in the user domain kernel, but the shutdown work that gets scheduled never actually gets called. I''m glad someone else is seeing this same problem now :-) Like you, it worked a number of times in a row, then would fail, and it didn''t seem to

Hello, I want to do comparative study between xen and kvm during live migration of vm.analysis of downtime and also using wireshark and netperf tool to perform analysis, what else can be done? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

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, 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

Hi all, I''am having problems using Xen 3.1. I''d like to use live migration, in a full virtualization environment (VT). First, when I migrate a guest domain, the vnc port is no longer available as soon as the guest migrated. I''m using drbd 8 to be able to live migrate the VM without using shared file system. I''ve modified xm utils to allow xen changing drbd

Hi, I am trying to build a rock solid XEN High availability cluster. The platform is SLES 11 SP1 running on 2 HP DL585 both connected through HBA fiber channel to the SAN (HP EVA). XEN is running smoothly and I''m even amazed with the live migration performances (this is the first time I have the chance to try it in such a nice environment). XEN apart the SLES heartbeat cluster is

Good morning, I installed 3 fedora core 7 machines with xen 3.1 Two machine (hp dl 360) are identical and windows guest live migration works fine. One of them is a HP dl 580 and live migration from/to hp 360 does not work. Stopping and restarting guests works in any case also if hardware is non identical. I read somewhere machine must be identical for live migration: is it true ? Why live

I can't get xen live migration to work - CentOS 5.6.

Hi, I'm having a hard time to figure how to perform Xen live migration using the python API with the same rate of success than virt-manager. # virsh version Compiled against library: libvir 0.8.3 Using library: libvir 0.8.3 Using API: Xen 3.0.1 Running hypervisor: Xen 3.2.0 The goal is to have the migration done in only one call, including a definition in the remote xend and undefinition
