[Putting libvirt-users back on CC] Yep, this is a pretty serious fail on my account, the code assumes SPICE needs a DRM render node every time one isn't defined within the XML due to a missing check for presence of the <gl> element. I stripped the XML you sent me to the bare minimum to demonstrate a reproducer: ... <graphics type='spice' autoport='yes'> <listen type='address'/> <image compression='off'/> </graphics> <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> ... Let me know whether you want to create a BZ/fix the bug/both otherwise I'll take care of everything and mention you in the commit message. Thanks, Erik

[libvirt-users] connecting two vm in a network
by daggs 06 Dec '18

06 Dec '18

Greetings, my router is running under a vm, I want to start another vm on that host and have to connected to the router vm in the same manner the host connects to the vm router. looking at the docs, I think that guest private network is what I need. thing is, from what I see, I need to define an ip and such. that's what the router suppose to provide so I'm not sure what exactly I need to configure and how. what is the correct config to achieve what I need? Thanks, Dagg.

[libvirt-users] no drm render nodes available

Hi, I get this error when trying to start a vm using spice as the graphics: "error: internal error: No DRM render nodes available" I can't seem to figure out what could be going on, since it worked just a little while ago. Using arch linux, and libvirt from git (4.10.0.22.g6a6925b9b7-1). -Michael.

[libvirt-users] XML-RPC

Hi all, I have 2 Centos servers running libvirtd. They are running using peacemaker cluster. After I had to reboot server 1, I can't no longer start VMs on server 2. I'm getting the following error message: error: Failed to start domain testvm error: internal error: Process exited prior to exec: libvirt: XML-RPC error : Failed to connect socket to '/var/run/libvirt/virtlockd-sock': Connection refused I can see that the deamon is listening on the port. I also couldn't find any further information in any logfile. Any idea? Thanks, Markus

[libvirt-users] How to get list of CPUs compatible with the host CPU and vendor?
by Milan Zamazal 03 Dec '18

03 Dec '18

Hi, I'm trying to use virConnectGetDomainCapabilities to get the list of CPUs compatible with the host CPU. I would like to further limit the list to CPUs of the same vendor as the host CPU. How can I do that? I tried to use virConnectBaselineCPU with <vendor> element and checking whether I obtain the same CPU, but that doesn't filter out CPUs without any vendor such as `kvm64' or `pentium'. Thanks, Milan

[libvirt-users] virsh console and other language keymaps
by Michael Taboada 30 Nov '18

30 Nov '18

Hi, I've got a small vm server running kvm + libvirt, and I made a simple shell script that allows users to ssh in and control their vms (power off, etc). However, one of my users uses the french canadian keyboard layout on her home computer, and upon being told "escape character is ^]" expected to need to press ctrl+right-alt_] (] being in the same location it is on a US keyboard). This is because on a french canadian layout, the right bracket key is in the same spot at on US layout, but needs to press right alt with it or it is the c-cedilla key. However, upon pressing ctrl+right-alt+c-cedilla, nothing happens (even this is ctrl+right bracket on a canadian keyboard). Instead, pressing ctrl+c-cedilla on her canadian french keyboard exits the console as if it were using a US layout. My question: how to make it so pressing ctrl+(canadian ]) works? Is this something that has to be done on the vm side, or on the host side, or maybe on the client ssh side? I'd prefer it be something thast can be different based on who is using the virsh console command since me, as the admin, may need to help with the console at some points, and my keyboard is US, so I have no c-cedilla or canadian right bracket key, but she does. Thanks, -Michael.

[libvirt-users] Unable to configure libxl's memory management parameters
by Mathieu Tarral 29 Nov '18

29 Nov '18

Hi ! I'm trying to get a working installation of Xen 4.11 from source, with Libvirt. I managed to compile, install and boot on Xen so far. But when I start the libvirt daemon, it fails with the following error: info : libvirt version: 4.1.0, package: 5.fc28 (Fedora Project, 2018-08-23-19:00:58, buildvm-19 error : libxlDriverConfigNew:1644 : Unable to configure libxl's memory management parameters error : virStateInitialize:775 : Initialization of LIBXL state driver failed: no error error : daemonRunStateInit:837 : Driver state initialization failed So there are 2 things here: - why libvirt is unable to configure Libxl ? where should i look for any clues ? - "Initialization of LIBXL state driver failed: no error" it looks like a bug in Libvirt, if it fails, an error message should be reported Thank you. -- Mathieu Tarral Sent with ProtonMail Secure Email.

[libvirt-users] Sasl+tls setup
by Anastasiya Ruzhanskaya 28 Nov '18

28 Nov '18

Hello everyone, I am trying to set up sasl authentication in virt-manager. I read in one existing bug, that it is better to use tls for encryption and sasl for authentication, but not use sasl for both. I configured tls, it was fine. Then I created a user "u" on server and modified libvirtd.conf. I set auth_tls = "sasl" there and mech_list: scram-sha-1 in sasl2 config for libvirt. The output of sasl: u@ubuntu2:~$ sudo sasldblistusers2 -f /etc/libvirt/passwd.db u@ubuntu: userPassword Then I connect to server using tls and entering as the user u. Then I have the following message: Unable to connect to libvirt qemu+tls://u@192.168.246.135/system. authentication failed: authentication failed What are the correct steps to set up everything right. I just followed this: set up tls, set up user, modify config file, relaunch and connect.
