similar to: Updating domain XML issue

Okay, let's try this another way... how are people dynamically attaching/removing cdroms from guests, without requiring a guest restart?

Hello, I'm trying to using virsh update-device to update the CDROM from type='file' to ceph rbd iso with type='network'. But I always get error: Failed to update device from disk error: internal error: unable to execute QEMU command 'change': error connecting: Operation not supported I'm using libvirt-libs-3.10.0-1.el7.x86_64 with centos7.4 my original cdrom xml:

Dear Michal After I fix the local libvirt master branch follow your patch, and build rpm for CentOS 7.4. virDomainUpdateDeviceFlags as bellow: ================================================ 2018-02-27 09:27:43.782+0000: 16656: debug : virDomainUpdateDeviceFlags:8326 : dom=0x7f2084000c50, (VM: name=6ec499397d594e f2a64fcfc938f38225, uuid=6ec49939-7d59-4ef2-a64f-cfc938f38225), xml=<disk

Miscellaneous fixes to: - Handling of Ceph drives now works end-to-end (RHBZ#1026688). - In particular, you can now use rbd:/// URIs in guestfish (and they work). - Parse Ceph & NBD network drives from libvirt XML correctly, so that existing domains with Ceph/NBD drives can be added (eg. using guestfish -d option). - Add more testing of the above.

I'm having some trouble creating KVM domains with RBD block devices using virsh. I've managed to get virsh to define the domain, but it gives an error when trying to start the domain: error: Failed to start domain test0 error: internal error process exited while connecting to monitor: char device redirected to /dev/pts/3 kvm: -drive

Hi, I'm trying to build an active/active virtualization cluster using a Ceph RBD as backing for each libvirt-managed LXC. I know live migration for LXC isn't yet possible, but I'd like to build my infrastructure as if it were. That is, I would like to be sure proper locking is in place for live migrations to someday take place. In other words, I'm building things as if I were

Hello, I would like to use RBD Format 2 images so I can take advantage of layering. However, when I use "qemu-img create -f rbd rbd:data/foo 10G", I get format 1 RBD images. (Actually, when I use the "-f rbd" flag, qemu-img core dumps, but it looks like that feature may have been deprecated [1]) Is there any way to have qemu-img create RBD Format 2 images or am I better off

Hello everybody, This is a cross post to libvirt-users, libguestfs and ceph-users.

Hi, I'm trying to run virt-sysprep against a disk in Ceph RBD storage but I appear to be unable to do so. The commands (bold) and outputs I've had are: On Ceph node: *virt-sysprep -a rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001* libguestfs: new guestfs handle 0x113b060 rbd://localhost/libvirt-pool/ubuntu-12-04-beanstalk001: No such file or directory libguestfs: trace: close

Eric, Well, in case where several servers may start the same virtual machines after a reboot for exemple. http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-August/003887.html I've seen this hook here : http://www.wogri.at/en/linux/ceph-libvirt-locking/ But it's a hook... Yes, I may try to write a patch. My coding skills are surely not as good as yours but I 'd be glad to make

Hi everybody, my background: I'm doing Xen since 10++ years, many years with DRBD for high availability, since some time I'm using preferable GlusterFS with FUSE as replicated storage, where I place the image-files for the vms. In my current project we started (successfully) with Xen/GlusterFS too, but because the provider, where we placed the servers, uses widely CEPH, we decided to

Hi, I've recently been working on setting up a set of libvirt compute nodes that will be using a ceph rbd pool for storing vm disk image files. I've got a couple of issues I've run into. First, per the standard ceph documentation examples [1], the way to add a disk is to create a block in the VM definition XML that looks something like this: <disk type='network'

how to use python-guestfs to access rbd device? The function i found is g.add_drive_opts, but i dono know how it receive ceph's configuration. I found this link http://rwmj.wordpress.com/2013/03/12/accessing-ceph-rbd-sheepdog-etc-using-libguestfs/ Is that the only way i should use to access ceph rbd? Can we use python-guestfs to get the same effect? Thanks
