Anybody can help on linux_s3 (kvm autotest)?
When running the testcase linux_s3 to test kvm, we constantly got
'bash: echo: write error: Resource temporarily unavailable'.
This testcase can be found at
autotest/client/tests/kvm/tests/linux_s3.py
(or autotest/client/tests/kvm/kvm_tests.py in the old version).
The testing command is:
'chvt %s && echo mem > /sys/power/state && chvt %s' % (dst_tty,
src_tty)
e.g.
'chvt 1 && echo mem > /sys/power/state && chvt 7'
Is there any chance that the 'echo' command is executed before 'chvt
1' took full effect? (Just my wild guess.)
I'll appreciate your help.
Regards,

There was a bug in virtio-balloon, fixed in 2.6.30, that prevents proper
suspend-to-RAM.
Can you share dmesg output after the failure?
