libvirt broken since last update: "cannot parse CPU map for x86 architecture"
Closed, ResolvedPublic

Description

Trying to start an existing VM with virt-manager, I get : internal error, cannot parse CPU map for x86 architecture.

libvirt version : 4.4.0-19

Detailed log:

FWIW : When I tested it was working. I made another test with libvirt 4.5.0 (D3268) and on my machine I face no issue with it (unlike gnome-boxes which doesn't want to work).

I get this too since Friday's sync.

I am also having this problem since the update. Rolling back the update fixes it for the time being for me.

Also ran into this issue yesterday. Tried to create new VM based on an exiting qcow2 image in Virt-Manager. Issue came up when I used the template thing to choose the OS (win 8.1 in my case). Even without the exiting image no media attached the error persists.
Used the generic template to with the exiting image and Virt-manager could create the machine. With other templates like CentOs 7.0 I didn't encounter the issue .
Can't offer a workaround for exiting machines but maybe this can narrow down the issue

What occurs when you do this:

  • Stop libvirtd service
  • sudo rm -rf /var/cache/libvirt/qemu/capabilities
  • Restart libvirtd
  • Try loading the VM again

Actually scrap that, I'll push an update and one of you can test it for me

There's a problem in the /usr/share/libvirt/cpu_map.xml file which shipped. From the libvirt logs:

2018-07-14 01:29:02.627+0000: 17883: error : x86FeatureParse:928 : internal error: CPU feature ssbd already defined
2018-07-14 01:29:02.627+0000: 17883: error : cpuMapLoad:125 : internal error: cannot parse CPU map for x86 architecture

There are a couple entries in the xml related to "ssbd" which are duplicated, causing the error. Removing the duplicates allowed me to start up my virtual machine, but I ran into another cpu_map related error later.
I replaced the file with the one from the libvirt master branch and haven't had any issues for the last couple days.

Someone try this and tell me whether it fixes the issue:

sudo eopkg install https://packages.solus-project.com/unstable/libv/libvirt/libvirt-4.4.0-20-1-x86_64.eopkg

Installed no issues
tested:

  • created new VM with Win 10 template
  • Created a CentOs 7 Vm deleted the entry (xml definition) did not delete the storage, created a new VM entry with exiting storage

not tested:

  • start a VM created in the previous version of libvirt (switched machines yesterday)

This is maybe of no use for you but for me it doesn't make a difference: libvirt was working before and it is still working now.
I can run my test VMs from virt-manager or directly from qemu but gnome-boxes doesn't want to work (tested with this version of libvirt, the rebased libvirt 4.5.0, gnome-boxes 3.28.4 from the repo and a local build of gnome-boxes 3.28.5).
