RFE: virt-manager should get supported devices/limits from qemu/libvirt
Last modified: 2014-03-16 23:22:29 EDT
Description of problem:
I have a VM. I added network adapters until it had 12.
When attempting to start the domain, I get:
Traceback (most recent call last):
File "/usr/share/virt-manager/virtManager/engine.py", line 588, in run_domain
File "/usr/share/virt-manager/virtManager/domain.py", line 150, in startup
File "/usr/lib64/python2.6/site-packages/libvirt.py", line 300, in create
if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)
libvirtError: monitor socket did not show up.: No such file or directory
Further investigation into the qemu log shows:
LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-kvm -S -M pc-0.11 -enable-kvm -m 500 -smp 1 -name splat-rhel5 -uuid 82099dd9-86c8-d9a0-28c8-df76c6cf4638 ...
qemu: Too Many NICs
If qemu has a limit to the number of network cards, virt-manager shouldn't
let you exceed it.

Also need to handle 32-bit memory limit.
This message is a reminder that Fedora 13 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 13. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '13'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 13's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 13 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Stil relevant, moving to rawhide
This is kind of a long project, since just hardcoding this stuff in virt-manager isn't sustainable. What we need is qemu reporting capabilities which libvirt passes on to apps, so we can determine limits introspectively.
Moving to upstream tracker

Keeping this bug open isn't going to accomplish anything unfortunately: there hasn't been much movement at the libvirt level towards a comprehensive capabilities reporting API, but when it exists virt-manager will use. Until then, just closing this
