At least currently there is a common probelm across LE and BE KVM runs

qemu-system-arm: -drive if=sd,cache=writeback,file=kvm.qcow2: could not open disk image kvm.qcow2: Could not open 'kvm.qcow2': No such file or directory

Hongbo can you talk with Anders, he can help you get up to speed on this bug.

Mike, I was working on trace tools in the past days, and will spend some time slots on the bugs in my hand since this week.

[Hongbo Zhang (hongbo-zhang)]

for linux-lng-arndale-be:
the first failure is "kvm-init-1 fail", i.e. no "Hyp mode initialized successfully" is found in the dmesg, all the follow failures are meaningless.

solution may be:
1. create a separate bug for kvm initialization on be, and
2. add sanity check in the test script, if former step fails, cancel all the following steps which depends on the former one.

[Victor Kamensky (vkamensky)]

There is some disconnect here. KVM never
worked for V7 BE before. We have card to address
that:
  [Linaro Cards] (LNG-267) BP: KVM in BE mode, 32-bit
which is work in progress. Also please see proposed
set of patches and feedback:
  https://lists.cs.columbia.edu/pipermail/kvmarm/2014-February/008039.html
IMHO this bug should be closed and LNG-267 tracked
instead.

Thanks,
Victor

Thank you Victor for your information. I will close this bug.

[Hongbo Zhang (hongbo-zhang)]

Close this bug as Victor said, this is a work in progress and should be closed.
