Hello, I''m running XEN 3.0.3 on RHEL5 2.6.18-53.1.4.el5xen. I used to start the vm with "xm create myvm -c". I see the boot during a couple of second, then, it freeze. The console is freezed, not the vm, a couple of second later, I can ssh the vm without any problem. "xm console myvm" also display a freezed state. This is an extrat of the console : # xm create myvm -c Using conf...

...d into the backend but given as input at compile time. I have some vague ideas on how I could implement this, but would like to ask for your ideas in order to keep me from going too far in a wrong/cumbersome direction. The first option that came into my mind is adding a new intrinsic "llvm.myVM.call_native(i32 %funcIdx, ...)" and then linking at compile time a module that looks like define void @foo(i32 %a) { call @llvm.myVM.call_native(i32 1, i32 %a) } define void @bar(i32 %a, i32 %b) { call @llvm.myVM.call_native(i32 2, i32 %a, i32 %b) } ...

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

..., I am looking for a solution for live backups of running KVM hosts. I recently read this article which highlights the following method: http://www.linux-kvm.com/content/first-look-virtual-machine-online-disk-snapshots-coming-fedora-18 1. virsh snapshot-create-as to create the snapshot 2. cp myvm.qcow2 myvm-backup.qcow2 to copy off the now read-only backing image file 3. virsh blockpull to merge the base and snapshot images together into a single image again Is this functionality only available in qemu 1.1? I am using Ubuntu 12.04 LTS on production servers which only includes qemu 1.0.x...

...so oVirt. Recently, following updates, VMs not handled by oVirt have been deleting themselves after they shut down. Previously to this, I have not had any problems of this nature. I cannot say whether the problem is coming from oVirt updates or not. I am creating a VM using "virsh define myvm.xml" on the server, starting it through virt-manager on my local PC, performing work inside the VM and then closing down the operating system inside the VM, and then once it has completed shutting down it shows "Shutoff" as the status in virt-manager and then maybe 5 seconds later it...

I use KVM on two identical centos5 hosts. I can live migrate the virtual machines from one to the other and it works great. Once I do this, I can see VM definitions on both hosts using virt-manager or virsh list --all On one machine the VM is running, on the other it reports "shut off". The disk images are accessible to both host machines and I want to have only one running a the time

...u mean in the case of a host crash, and if so what filesystem ? If you are using NFS at lesat so you shouldn't need to know the file names, there is the ability to tell the NFS server to release all locks associated with a dead host. > I do an  sha256 hash from /var/lib/libvirt/images/lock/MyVM.img but I > don't get the same hash code form virtlockd ? It uses the sha256 has of the filename. How did you generate your hash ? If using shell make sure you don't include a newline ie you want echo -n /var/lib/libvirt/images/lock/MyVM.img | sha256sum not a plain 'echo'...
