Hi folks I deploy a two Dell PowerEdge T300 to test Virtualization with kvm+drbd+heartbaet. The KVM drbd and heartbeat work properly. However, I have doubt!! When the primary node has down, the secondary node start the VM that has original running on primary node... So, this required a full stop of hole system... This is not we wish here... Is there something way to live migrate VM from

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

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

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

I am trying to run a new server with centos + xen using centos xen packages. After installation, we had to install a hardware raid card (areca) on the machine, and thus reload the os. It so happens the drivers shipped aren''t compatible with xen kernel, so i was forced to compile xen from source to compile areca drivers. Now with system running under compiled xen, i cannot boot my old

Hi, I have been getting the following error (logged in /var/log/xen/xend.log) when I try to migrate a VM from one particular host to the other (the reverse migration works fine). My system was working fine for a long time (i did several migrations in both the directions). I am using Xen-3.4.3 (installed from source code) with CentOS 5.4. I am using drbd to replicate the disks.

Hi, Is vfb working well lately? I thought I''d test it out on ia64 and it works great, but only once per boot. If I stop the domain and restart it, I get the following: Error: Device 0 (vkbd) is already connected. To make sure this isn''t an ia64 anomaly, I tried it on an x86_64 system. Same thing, works the first time, reboot the domain and it''s broken. I see

I''ve just uploaded 0.9.11-pre12 of the GPL PV drivers for Windows. Since -pre10 (and -pre11) I''ve fixed a heap of crashes that were plaguing xennet under load, and also rewritten the interrupt/event distribution logic to improve performance. Under windows 2003 I can now get network speeds of 1-2Gbit/second TX and 600Gbit/second RX, which is considerably better than I was

Hi, I have a problem with a dom0 which is unable to launch my domU : all my dom0 are Debian Lenny amd64 with Debian kernel 2.6.26-2-xen-amd64 and xen-hypervisor-3.2-1-amd64. Then all domU (PV) are Debian Lenny amd64 too, with vanilla kernel 2.6.29.6. So, this new dom0 can''t launch any domU which are working on an other dom0. Software is same on both dom0, and hardware is near the
