similar to: Xen LVM DRBD live migration

Hi, I have written the following code which works fine step<-5 numSim<-15 N<-double(numSim) A<-double(numSim) F<-double(numSim) M<-double(numSim) genx<-double(numSim) for (i in 1:numSim) { N[i]<-20 PN<-(runif(N[i], 0, 1)) A[i]<-sum(ifelse(PN>0.2, 1, 0)) PF<- runif((A[i]*0.5), 0, 1) F[i]<-sum(ifelse(PF>0.2, 1, 0)) PM<-

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 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

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.

Hi, since I upgraded from Lenny, DRBD VBD scripts not works at all. This config works : disk = [ 'phy:/dev/drbd/by-res/ads-disk,xvda,w' ] But his one doesn't work at all : disk = [ 'drbd:ads-disk,xvda,w' ] I obtain this error : # xm create ads.cfg Using config file "/etc/xen/ads.cfg". Error: Device 51712 (vbd) could not be connected. Hotplug scripts

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 all, I''d like to know if it''s possible to have more verbose output when running a block-prefix script. Other than xend.log. To be more specific I''d like to use bash -x to see why I''m running into the following error: > # xm create -c host.cfg > Using config file "host.cfg". > aa:bb:cc:dd:ee:ff > Error: Device 51712 (vbd) could not be

Hi all, I''m trying to get a pci card working on a guest os (ast01) on dum0 I hided the pci card w/: # modprobe pciback hide=''(0b:08.0)'' then added this line to the guest os config file (/etc/xen/ast01) pci = [ "0000:08:0e.0" ] Whenever I try to start it fails w/: # xm create ast01 Using config file "/etc/xen/ast01".

Hello, i have two xen hosts servers configured to support migration of domus, but when i try to migrate, the command never ends, i can see on the remote server the machine with xm list but the machine is not accesible, and on the own server i see migrating-{machine_name} and i have access to it. Every server have one nic, with public ip (that is using with xenbr0), and i have a virbr0 configured

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.

Hi Sriram, Once again, thanks for your timely reply.... I tested as your suggesstion and i found that i don''t have any file in the location "/var/lib/xen" [root@globushead xen]# pwd /var/lib/xen [root@globushead xen]# ls -ll total 0 Further i tested the command "xm save " and results as follows Terminal 1: xm save -c TestVM1 TestVM1.chkpt

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.

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.

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
