[libvirt] [PATCH 0/4] qemu: fix restore domain with bypass cache flag

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 src/util/iohelper.c | 98 +++++++++++++++++++++++++++++++---------------------- src/util/virfile.c | 2 +- 2 files changed, 59 insertions(+), 41 deletions(-) -- 1.8.3.1
