similar to: virsh list shows no vm after downgrade

Hi, I was running libvirt 1.2.2 and qemu 2.0 which are from icehouse cloud archive repo on ubuntu 12.04, "virsh list --all" showed correct instances after launching several VMs, Then I just downgraded libvirt to 0.9.13 and qemu to 1.0, but kept the VMs running. However, when I run "virsh list --all" after downgrade, I can't see any VMs. Seems that the old version libvirt

Hi, My nova-compute nodes was running libvirt 0.9.13 and QEMU 1.0, after libvirt was upgraded to 1.2.2, the VMs launched by libvirt 0.9.13 can't attach volume any more, i.e. "nova volume-attach <vm-uuid> <volume-uuid>" doesn't work. But before the libvirt upgrade, the same VM can attach volume disk. I did some debuging and find that, it failed in QEMU when try to

scenario: i run a mix of libvirt 1.1.1 and 1.2.2 on the source hosts, 1.2.2 on the destination hosts qemu: 1.5.0+dfsg-3ubuntu5.3~cloud0 on all the hosts openstack havana and icehouse description: i have many compute nodes running libvirt+kvm, when i try to migrate guest that were created months ago it fails, if i create a vm and then migrate it works the problem is that libvirt cannot

Hi, I tried to enable virtio-blk data plane feature for VMs in my openstack environment, the hypervisor is ubuntu 14.04, libvirt 1.2.2 and QEMU 2.0. As nova doesn't support that parameter yet, I did belows 1. nova boot a VM with raw disk image. 2. nova stop the VM. 3. run "virsh edit <instance-id>" on the hyprvisor node, and adding below into instance xml just before

Hi Kashyap, Here I want to test and see how much I/O performance could be improved by virtio-blk data plane feature. Yes, this is a dirty way to enable it :-), You mentioned using newer libvirt, is there parameter similar "x-data-plane=on" in new version libvirt? Please let know me you if you have better solution.

Hi Eric, Thanks! You are right, I missed declaring namespace, now, the <qemu:commandline> is saved after virsh edit. However, both namespace and <qemu:commandline> tag are lost after I run "nova start" to launch the VM. Any idea that how could I make this qemu command take effect ? Regards, CY.

Hi guys, one of my VM has disappeared in libvirtd. I still can see the process with ps and the configuration file is as well there. But it is not displayed or found with virt-manger/virsh. virsh list shows only 4 of 5, but there is no real error message. I restarted the daemon without solving the problem. Any idea what to do?

Hi. I've tried Samba 3.4.3 and it upgraded my passdb.tdb file. After testing I concluded that I'm not going to upgrade to 3.4.3 yet, because 'getent passwd' was broken in recent BlastWave Solaris packages: http://wiki.blastwave.org/forum/viewtopic.php?f=5&t=447&start=0 Now, after I downgraded the Samba back to 3.0.32, client connections started to malfunction. I saw

Ian, Keir, This patch is to boot 32-bit VMX guest on the 64-bit host. Double-compile is used to make both 64-bit guest and 32-bit guest can work, the shadow page-table uses current 64-bit shadow code''s structure to simulate 32-bit guest''s 2-level page-table.

Good day list, I have a problem with ATA Handy Tone 286. It has been unsuccessfully downgraded via HTTP. Seems like during downgrade there was a problem with connection, because now it's not responding at all. There is no way to get to it's voice menu via phone (by pressing button on it). The button is just flashing ... Could anyone suggest any way to bring that device back to life.

Let''s say that there is a web application which comes in several different plans. Each plan has a different number of users and content items allowed for an account. Obviously we can allow the user to upgrade to a higher level plan by just increasing their limits but how do we handle downgrades? If the user is only allowed x items on the downgraded plan and they currently have

To avoid MSR save/restore at every VM exit/entry time, we restore the x86_64 specific MSRs at domain switch time if modified. In VMX domains, we modify those upon requests from the guests to that end. Note that IA32_EFER.LME and IA32_EFER.LMA are saved/restored by H/W on every VM exit. For the usual domains (i.e. dom0 and domU), those MSRs are not modified once set at initialization time, so we
