[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.

Hi, Is there anybody who got the usb-redirection working with remote-viewer on Windows? If I install remote-viewer, the option to redirect usb devices is grayed out in the menu. Greetings, Dominique.

[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. Thanks! -Ken

[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

[libvirt-users] removing PS/2 keyboard
by Tadas 23 Nov '15

23 Nov '15

Hello lists, I wonder, is there a way to remove a PS/2 keyboard from a guest and leave it only with USB bus one? Problem is that if i edit guest (via virsh edit) and change keyboard bus from ps2 to usb, I end up with two keyboards: ps2 and usb one. --

[libvirt-users] libvirt prepare and start hooks not callled
by Sundar Nadathur 20 Nov '15

20 Nov '15

Hello, I am using RHEL 7.1 and libvirt 1.2.8. My intention is to intercept the prepare and start hooks of libvirt during VM placement to inject a virtio PCI device into the VM's domain xml. I placed a python script with execute permissions in /etc/libvirt/hooks/qemu. In there, I opened a log file to record the arguments received: log.write("avfd called with args: %s\n" % sys.argv) But all I get in the log file is: avfd called with args: ['/etc/libvirt/hooks/qemu', 'vm1', 'started', 'begin', '-'] There are no prepare or start calls. Can somebody explain what it takes to fix this? Cheers, Sundar ________________________________ Confidentiality Notice.
