Re: [Bug 690042] Re: libvirtd tries to disable ipv6's accept_ra even when ipv6 is disabled outright in the kernel

2011-06-30 Thread Anomaly256
Simply compile a kernel without ipv6 support.

Libvirt blindly assumes the /proc/sys/net/ipv6/* entries exist and fails
to gracefully continue when they are not writable.

 Can you please add more steps to reproduce this bug? It's not clear to
 me when this happens although I have found the problem in the source
 code. It is hardly to test it even when I make change to code.

Re: [Bug 690042] Re: libvirtd tries to disable ipv6's accept_ra even when ipv6 is disabled outright in the kernel

2011-06-30 Thread Anomaly256
To be more specific in order to reproduce:

Compile/switch to a kernel without ipv6 support (don't worry about the
specifics as to why someone would do this, it's come up a few times
where I've had to ie buggy application support, administration of
machines also acting as firewalls, etc)
Then use virsh, virt-manager, or whatever other libvirt mechanism to
provision a new virtual machine.

Libvirt will try to change some interface/protocol settings by echoing
values to /proc/sys/net/ipv6 entries during the provisioning/launch
process when activating the virtual network configs but will fail as
these entries don't exist on such a kernel.

At this stage the provisioning/launching of the new virtual machine
died out of hand where it should instead detect that there is no ipv6
support and continue without attempting to make these changes.

There are actually probably a few areas where libvirt tries to alter
procfs or sysfs entries blindly where it should be testing for it's
ability to do so first and at worst gracefully ignoring the errors in
doing so as they aren't critical for actually launching the virtual
machines or the virtual network configurations

Yup.

Yes, dozens of them.

[Bug 791454] [NEW] Oneiric Alpha1 Server x86 and x86_64 RAID1 Test Failed: Device need to be readded manually

2011-06-30 Thread Launchpad Bug Tracker
Kate Stewart (kate.stewart) has assigned this bug to you for mdadm in Ubuntu:

When testing RAID1 on x86 during step 16 'i', after reattaching the
second disk not all arrays came back.  Two devices needed to be readded
manually.  Reporting this bug as mentioned in step i.  I was testing
using a KVM VM with two qcow2 disk images and virtio.

If there is any further details I can provide please let me know.

Same setup failed for x86_64.

[Bug 804105] [NEW] package qemu-kvm-extras-static 0.12.3 noroms-0ubuntu9.9 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

2011-06-30 Thread indymaynard
Public bug reported:

Attempted to clean (apt-get clean) and uninstall then reinstall package.
The error shows everytime I update or install/uninstall a package.
/var/log/apt/term.log shows:

Setting up qemu-kvm-extras-static (0.12.3+noroms-0ubuntu9.9) ...
update-binfmts: warning: /var/lib/binfmts/arm does not exist; nothing to do!
start: Job failed to start
invoke-rc.d: initscript procps, action start failed.
dpkg: error processing qemu-kvm-extras-static (--configure):
 subprocess installed post-installation script returned error exit status 1

Not a show-stopper, but certainly annoying.
