Can somebody knows how to enable virtio-scsi-data-plane in libvirt for specific domain? I know that i need to replace "-device virtio-scsi-pci" with "-object iothread,id=io1 -device virtio-scsi-pci,iothread=io1" in qemu, but how can i do this in libvirt? -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru

[libvirt-users] How to disable kvm_steal_time feature
by Piotr Rybicki 30 Nov '15

30 Nov '15

Hi. I would like to workaround a bug, when after live-migration of KVM guest, there is a 100% steal time shown in guest. I've read, that disabling 'kvm_steal_time' feature should workarund this bug, but i can't find a way to disable it in libvirt's domain xml file. Tried in <cpu> section: <feature policy='disable' name='kvm_steal_time'/> but that doesn't work. Also, couldn't find any related information in libvirt documentation. Google helps neither. How can I disable this feature? Thanks in advance. Piotr Rybicki

[libvirt-users] virsh uses internally qemu-img ?
by Lentes, Bernd 30 Nov '15

30 Nov '15

Hi, i read that virsh uses internally qemu-img (http://serverfault.com/questions/692435/qemu-img-snapshot-on-live-vm) Is that true ? so snapshotting a running vm with virsh or qemu-img is the same ?

[libvirt-users] New vs old API usages
by Shahar Havivi 29 Nov '15

29 Nov '15

Hi, Currently I am using the latest libvirt API listAllDomains() to probe for domains. I may need to fall back to older API for old libvirt server such as: listDefinedDomains() and lookupByName() instead of listAllDomains(). Is there any disadvantage to using listAllDomains instead of listAllDomains or its the same results via different API? Thank you, Shahar.

[libvirt-users] SOLVED: failed to connect to the hypervisor
by Ken D'Ambrosio 25 Nov '15

25 Nov '15

Ubuntu, for the loss. Turned out to be an apparmor issue; as I hadn't touched the profiles, it must've been something else going on. -Ken ------------------------- original issue ---------------------------- When I try, I get this: root@kilo-VirtualBoxHost:~# virsh -c vbox:///session error: failed to connect to the hypervisor error: internal error: nsIEventQueue object is null ---------------------------------- The part that puzzles me is that it *used* to work, but no longer. "virsh -V" shows me running libvirt 1.2.2, with VirtualBox enabled. I'm running stock Ubuntu VirtualBox v. 4.3.10. I've rebooted; I've tried running it as different users. Googling comes up with some five-year-old Solaris patch discussions. My /var/log/libvirt/libvirtd.log shows stuff like this: 2015-11-25 02:21:39.381+0000: 3893: error : virNetSocketReadWire:1454 : End of file while reading data: Input/output error 2015-11-25 02:26:38.953+0000: 3897: error : vboxInitialize:932 : internal error: nsIEventQueue object is null 2015-11-25 02:26:38.954+0000: 3893: error : virNetSocketReadWire:1454 : End of file while reading data: Input/output error Any pointers would be greatly appreciated.

[libvirt-users] esx/vcenter: create a domain inside an folder
by Cyrill von Wattenwyl 23 Nov '15

23 Nov '15

Hello at all Im trying to create a domain inside a folder: Host: foo.tld Datacenter: dc1 Cluster: cluster name1 Host: esx.tld Folder: folder/subfolder (inside Cluster bar.tld) URL: vpx://foo.tld/dc1/cluster%20name1/folder/subfolder/esx.tld I tried nearly every combination since the documentation is not 100% clear about that, but libvirt allways creates the domains inside vpx://foo.tld/dc1/ and not goes "deeper". My questions: - Is it even possible to create domains inside of a folder inside a cluster? If yes, how? - Could the whitespace in cluster name be a problem? - The user im trying to create the vms does not have permissions to view/change things on level datacenter/cluster/main folder. it can only view things in the subfolder. Could this be the issue? Thanks for your time and best regards, Cyrill
