Thanks. It does indeed look like a legitimate OSError in os.fork().
BTW, do you have any idea why the result dir has such a weird name?
/kvm-autotest/client/results/default/kvm_runtest_2.[RHEL-Server-5.3-64][None][1024][1][qcow2]<no_boundary.local_stg.RHEL.5.3-server-64.no_ksm.boot_vms.e1000.user.size_1024>/debug/post_vm1.ppm
And why sometimes a normal looking tag appears (in the log messages):
no_boundary.local_stg.RHEL.5.3-server-64.no_ksm.boot_vms.e1000.user.size_1024
Why all the [] and <> in the weird version? Did you somehow do that intentionally, or is it some sort of bug?
And why is 'None' there? The tag is supposed to be the test's 'shortname', which is determined by kvm_config.py
as it parses kvm_tests.cfg (or the config file you're using).
Normally the result dir should just be kvm_runtest_2.shortname, and in this case:
kvm_runtest_2.no_boundary.local_stg.RHEL.5.3-server-64.no_ksm.boot_vms.e1000.user.size_1024
