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 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? Here some info: Compiled against library: libvir 0.9.13 Using

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, 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

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

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.

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, 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 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.

Use the 'downgrade' option. https://access.redhat.com/solutions/29617 On Thu, Jun 1, 2017 at 1:46 PM, Anand Buddhdev <anandb at ripe.net> wrote: > We're using ansible to configure our CentOS 6 servers, and we have a > task to install a specific version of a package: > > - name: install thrift2 > yum: name=ripencc-thrift2-{{ version }} > > In this ansible

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

Personally, I would do one of three things: 1. Use the -m command to run 'yum install <version>' which /might/ work. 2. Uninstall the newer package and install the version you want. (Check the 'state' directive to do this.) 3. Pin that package version when creating the server/VM so as not to be updated. #3 is useful to us as we kickstart all our servers and VMs, and

hi guys, gals do you see this: ~]$ yum downgrade samba Resolving Dependencies --> Running transaction check ---> Package samba.x86_64 0:4.4.4-9.el7 will be a downgrade --> Processing Dependency: samba-libs = 4.4.4-9.el7 for package: samba-4.4.4-9.el7.x86_64 --> Processing Dependency: samba-common-tools = 4.4.4-9.el7 for package: samba-4.4.4-9.el7.x86_64 --> Processing

I tried, last night, to downgrade kdelibs, I think it is, to resolve the libplasma crash that we talked about yesterday... and yum told me there was no upgrade or downgrade. I'm sort of assuming that I'd have to go back to 6.4... unless I need to add a repo - the vault? wget it, and downgrade it locally? mark
