qemu-keymaps lacks en_us. REGRESSION: VMs do not boot out of Virtual Machine Manager any more

[Till Kamppeter]

I have updated from Quantal to Raring. Under Quantal I have set up several virtual machines using the Virtual Machine Manager and qemu/kvm. While under Quantal the machines always worked perfectly. After the update to Raring I cannot boot them any more. When I click the geen Play button to boot the selected machine I get a pop-up error message:

"Error starting domain: Unable to read from monitor: Connection reset by peer"

Clicking on "Details" gives me a Python traceback:

----------
Error starting domain: Unable to read from monitor: Connection reset by peer

Traceback (most recent call last):

Thanks for reporting this bug.

Could you please attach the xml definition for one of the domains which fails to start?

Log into the server which actually hosts the VMs and do

    virsh list --all
    virsh dumpxml <vm-name>
    sudo sed -i '/log_level/d' /etc/libvirt/libvirtd.conf
    echo 'log_level = 1' | sudo tee -a /etc/libvirt/libvirtd.conf
    sudo stop libvirtd
    sudo start libvirtd
    virsh start <vm-name>

Then attach /var/log/libvirt/libvirtd.log and /var/log/libvirt/qemu/<vmname>.log as attachments to this bug.

Thanks again.

I have executed the commands now and attach the requested files. Note that the commands to restart the daemon were

sudo stop libvirt-bin
sudo start libvirt-bin

for me.

[Serge Hallyn (serge-hallyn)]

Thanks for that info. It looks like you don't have qemu-keymaps installed. Could you show the result of

dpkg -l | grep qemu
apt-cache show qemu-keymaps
ls -l /usr/share/qemu/keymaps

The qemu-system-x86 package depends on qemu-common which depends on qemu-keymaps, so they certainly *should* be installed.

qemu-keymaps is installed but the file is missing:

 QEMU is a fast processor emulator: currently the package supports
 ARM, CRIS, i386, M68k (ColdFire), MicroBlaze, MIPS, PowerPC, SH4,
 SPARC and x86-64 emulation. By using dynamic translation it achieves
 reasonable speed while being easy to port on new host CPUs.

 This package provides keyboard maps to be used by the qemu-system
 package or QEMU derivatives.

[Serge Hallyn (serge-hallyn)]

Thanks. The problem stems from having qemu-keymaps installed from the linaro ppa. I'd made sure that the new qemu-keymaps package woudl replace the old qemu-linaro (from universe) qemu-keymaps package, but the ppa was never addressed.

the solution to this may simply be to remove qemu-keymaps frmo the linaro package, but I'm not sure.

[Serge Hallyn (serge-hallyn)]

Of course, qemu-keymaps coming from linaro may not be a problem if it would include the en_us map :)

could you please include your /etc/apt/sources.list.d/* files? I'd like to look at the source to determine who to talk to about the missing file. Unfortunately there is no way to file a bug against a package in a ppa (that I know of).

I have a file

containing

deb http://ppa.launchpad.net/linaro-maintainers/tools/ubuntu quantal main
deb-src http://ppa.launchpad.net/linaro-maintainers/tools/ubuntu quantal main

The machine is an x86_64 PC, no ARM.

> Of course, qemu-keymaps coming from linaro may not be a problem if it would include the en_us map :)

It does include en_us, it's just putting all the keymaps in a different directory to the one qemu is looking for (/qemu-linaro/ vs /qemu/)

[Till Kamppeter (till-kamppeter)]

The Linaro package is the problem, I did

sudo rm /etc/apt/sources.list.d/linaro-maintainers-tools-quantal.list
sudo apt-get update
sudo dpkg -P --force-depends qemu-keymaps
sudo apt-get install -f

and after that I could use my virtual machines again.

Oh, yes, I'm sorry - I had looked through the dpkg -L output, and just
missed it!

So the alternative to dropping qemu-keymaps from the linaro package
would be for the linaro package to at least add a symlink.

[Serge Hallyn (serge-hallyn)]

Should this be marked invalid or fix-released for the Ubuntu qemu and qemu-linaro tasks?
