The current recommendation from the

libguestfs usually needs qemu. However it only requires an emulator for the same architecture, not for all architectures. libvirt-daemon-kvm pulls in qemu which pulls in emulators for all architectures, as well as a bunch of other stuff we don't need at all like network interface support and nwfilter. There are no Fedora TCG-only arches, so drop the conditional section. I also made support

Compared to v3 this suggests: +Suggests: qemu-block-curl +Suggests: qemu-block-gluster +Suggests: qemu-block-iscsi +Suggests: qemu-block-rbd +Suggests: qemu-block-ssh which I missed in an earlier email from danpb.

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, A compilation failure happened when I tried building libvirt latest code on rhel8 Version: gcc-8.3.1-4.5.el8.x86_64 libvirt v5.9.0-352-g5e939cea89 Steps: 1. Clone libvirt source code 2. Create build dir, and run autogen.sh # cd libvirt # mkdir build && cd build # ../autogen.sh --build=x86_64-redhat-linux-gnu --host=x86_64-redhat-linux-gnu --program-prefix=

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, I am doing some experimentation with xen and Ceph and have a problem booting my guest when my disk = [] uses an alternate block script. Installation from a .iso was ok since the boot device was a file but now trying to boot from the rbd neither the hvmbuilder or pygrub can start as they treat the first value after target= as the /dev node to try and use. My disk parameter looks like: 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.

Hello everybody, This is a cross post to libvirt-users, libguestfs and ceph-users. I came back from FOSDEM 2016 and this was my 7th year or so and seen the awesome development around visualization going on and want to thank everybody for there contributions. I seen presentations from oVirt, OpenStack and quite a few great Redhat people, just like the last previous years. I personally been

Hi, I try to define an iscsi pool with virsh but I always get the following error : error :internal error: missing backend for pool type 5 (iscsi) And yet libvirt was compiled with iscsi support : configure: Storage Drivers configure: configure: Dir: yes configure: FS: yes configure: NetFS: yes configure: LVM: yes configure: iSCSI: yes configure: SCSI: yes configure:

Hello, I see there is an option with virsh attach-disk to set the cache to "none" for raw devices, but I can't find how to attach the disk with io=native (needed for performance reasons). The goal is to attach a disk online, directly with the proper performance settings. I know I can set this in virt-manager, but then I have to restart the VM to apply the change, so this is an

Hi, I'm using virsh to instance a VM in my environment, but I'm running on some issues. I created the following domain file: <domain type='kvm'> <name>demovm</name> <uuid>4a9b3f53-fa2a-47f3-a757-dd87720d9d1d</uuid> <memory unit='KiB'>4194304</memory> <currentMemory
