[libvirt-users] How to start guset os with specified IP address
by 落痕 15 Dec '15

15 Dec '15

Hi! Dear everyone. I met a problem with virsh. What should I do if I hope to start my guest os with specified IP address and guest os can be accessed by external computers? I tried to use route mode to configure my virbr0, but it cannot assign an IP to my guest os! If virbr0 are set NAT mode and act as a switch with dhcp, then the guest os cannot be accessed by external computer. note: Ubuntu server are install in host without xwindows, so I have to work with command line. Thanks!

Hi, i just upgraded to virt-manager 1.3.1 (Kubuntu 14.04 with getdeb). I can connect to a remote Hypervisor (libvirtd/KVM) but when i try to "open" a VM, virt-manager gives me the following error: ============================================================================== summary=Fehler beim Starten der Details: Namespace Vte not available for version 2.91 details=Fehler beim Starten der Details: Namespace Vte not available for version 2.91 Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 823, in _show_vm_helper details = self._get_details_dialog(uri, vm.get_connkey()) File "/usr/share/virt-manager/virtManager/engine.py", line 801, in _get_details_dialog obj = vmmDetails(conn.get_vm(connkey)) File "/usr/share/virt-manager/virtManager/details.py", line 367, in __init__ from .console import vmmConsolePages File "/usr/share/virt-manager/virtManager/console.py", line 30, in <module> from .serialcon import vmmSerialConsole File "/usr/share/virt-manager/virtManager/serialcon.py", line 32, in <module> gi.require_version("Vte", "2.91") File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 83, in require_version (namespace, version)) ValueError: Namespace Vte not available for version 2.91 ================================================================================= Any Suggestions ? virt-manager Verions 1.1.x-1.3.0 worked just fine.

[libvirt-users] Issues with installing Libvirt 1.2.7 on Ubuntu 12.04
by Waqas Riaz 09 Dec '15

Hi, I am trying to manually install libvirt 1.2.7 on Ubuntu 12.04 LTS (64bit). I have installed libxml2-dev libgnutls-dev libcurl4-gnutls-dev python-dev, but I am facing dependency issues for libdevmapper libraries. Is there any workaround for this dependency? OR is there any other way to install libivirt 1.2.7 on Ubuntu 12.04. Following is the output of the error #apt-get install libdevmapper-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

[libvirt-users] Destroy autostarted network on shutdown
by Jan Grashöfer 08 Dec '15

08 Dec '15

Hi all, I just ran into problem properly stopping a network. I have defined a network and network hook script to accomplish some preparations and cleanup. Testing my configuration (virsh net-start and virsh net-destroy) was successfully. Now I wanted to automate the lifecycle. Unfortunately I realized that an autostarted network has to be persistent and thus will not be destroyed (even if the host gets shutdown). As it won't be destroyed, my cleanup doesn't get executed and I run into trouble. What would be the preferred way to implement an autostarting and autostopping network? Thanks, Jan

[libvirt-users] virsh attach-device scripting ...
by Jean-Pierre Ribeauville 08 Dec '15

08 Dec '15

Hi, Did anybody ever try to script « virsh attach-device ...... < response.txt" in order to give virsh user and password needed when host is part of a ovirt cluster ? Cos , although I put in my response.txt two lines one for user the other for password , then it always asks question concerning password. ( username is correctly got from the .txt file.)

[libvirt-users] libvirt logging of virDomainAttachDeviceFlags()
by Jean-Pierre Ribeauville 07 Dec '15

07 Dec '15

Hi, When using « virsh attach-device ....." to add a channel device to a Guest , I see following entry in libvirt log : 2015-12-07 11:14:47.307+0000: 14551: debug : virDomainAttachDeviceFlags:10433 : dom=0x7f2a58252fc0, ........ Great !! But , when calling virDomainAttachDeviceFlags( ) from a C program , I got return code -1 but nothing appears related to virDomainAttachDeviceFlags( ) in the libvirt log file . Others libvirt calls of this C program are correctly logged . Did I misunderstand something ? To add traces I've added these lines within /etc/libvirt/libvirtd.conf log_level = 1 log_outputs="1:file:/var/log/libvirt/libvirtd.log" Thx for help. Regards, J.P.

[libvirt-users] virsh athentification failure
by Jean-Pierre Ribeauville 05 Dec '15

05 Dec '15

Hi, I wrote a C program running in a KVM host. Part of it adds a Unix Channel device in all Guests in order to have a dialog from Host to Guest. As long as my host wasn't part of an Ovirt cluster , all was running fine. I added my host in a ovirt cluster , and then , when running the script creating the channel device ( by using "virsh attach-device --persistent -live ....." ) , I got following error : Please enter your authentication name: Please enter your password: error: failed to connect to the hypervisor error: no valid connection error: authentication failed: Failed to step SASL negotiation: -1 (SASL(-1): generic failure: All-whitespace username.) What's the user/password I've to use then ? BTW , I've seen that following channel device was added to the Guest at its creation : /var/lib/libvirt/qemu/channels/ad1a8b0e-f8b6-4038-be3d-275f38e66eb3.org.qemu.guest_agent.0 What's used for ? I presume I cannot use for my private purpose ? I sent this topic to ovirt and libvirt mailing lists , cos I don't know which forum is the right one for this kind of subject. Thanks for help.

Hi there, I'm new to libvirt and I'm trying to install it on a Debian Jessie system. My goal is to create and use VMs from the command line. When I get to the $ make check (not as root) I am getting the message below. I am not sure if those "failed" messages should be corrected before starting to use libvirt, not sure how important they are. I will appreciate any hint or advise.
