[Bug 458521] Re: kvm crash when using virtio for network, hardy guest

[Dustin Kirkland]

** Description changed:

  Binary package hint: kvm
  
  I was running a kvm host with 5 virtual machines using jaunty. 1 running
  centos 5.4, 3 running karmic and 1 running hardy.
  
  I upgraded the host to karmic to test it and one of my virtual
  machines(the vm with hardy) crashs after some seconds of boot! I stack
  traced the kvm process and found a "virtio-net truncating packet" before
  process crash.
  
  No error in any log file. The VM just crash.
  
  I changed the model of network interface(the disk is still virtio) in
  VM.xml to rtl8139, redefined and started. The problem goes away.
  
  I don't know if it's a kvm bug or libvirt(regarding the bridge network)
  bug but definitely is a bug. All other VMs are running OK with virtio
  for both network and disk.

+ ===========================
+ Karmic Release Notes:
+ 
+ KVM Guest Crashes when Guest is Hardy and using Virtio Networking
+ 
+ Ubuntu 8.04 LTS (Hardy) KVM guests using virtio networking may crash,
+ when running on top of Ubuntu 9.10 (Karmic) hosts.
+ 
+ As a workaround, such guests should use either e1000 or rtl839 as the
+ networking model.  A fix for the bug is currently in progress and should
+ be addressed in an update to the qemu-kvm package in Karmic.
