It is not working currently. Error message is (with convinient wraps):
error: Failed to restore domain from tst6.sav
error: internal error: Child process (LIBVIRT_LOG_OUTPUTS=1:stderr \
/usr/libexec/libvirt_iohelper /vz/dev/libvirt/tst6.sav 0 0) unexpected exit status 1: \
/usr/libexec/libvirt_iohelper: failure with /vz/dev/libvirt/tst6.sav : \
Unable to read /vz/dev/libvirt/tst6.sav: Invalid argument
The problem is that saferead function being used by iohelper is not quite suitable
for direct reads. It's last read that is supposed to read EOF is not properly
aligned thus EINVAL is returned.
Nikolay Shirokovskiy (4):
iohelper: drop unused operation length limit
iohelper: simplify last direct write alignment
iohelper: reduce zero-out in align case
iohelper: fix reading with O_DIRECT
