[sheepdog-users] 答复: the windows 2003 server will cannot bootup before i reboot sheepdog

[redtone]

I have update sheepdog to v0.7.6-rc0
And update qemu to latest version v1.7.50

The windows guest cannot booted up. I also found centos 6.4 cannot boot up.

I use qemu-img convert to dump the sheepdog disk to a raw file. 
The guest can boot up normal with the dumped raw file.
      <disk type="file">
        <driver name="qemu" type="raw" />
        <source file="/root/kvm117_os" />
        <target dev="hda" bus="virtio" />
      </disk>
But cannot boot up with sheepdog disk
    <disk type="network">
      <driver name="qemu" type="raw" io="threads" cache="writeback" />
      <source protocol="sheepdog" name="kvm117_os">
        <host name="localhost" port="7000"/>
      </source>
      <target dev="hda" bus="virtio"/>
    </disk>

Do you think about the sheepdog driver in qemu ?

I use raw format not qcow2

Qemu version is 1.7.0.rc2 (sheepdog support auto-reconnect)

What format? raw or qcow2? I have recently fixed a issue about qcow2 over
sheepdog in qemu.

install the driver in 2003. the same issue will occur.

For a irrelevant suggestion that use 'virtio' as possible as you can for
better
performance and I assume you have already install virtio driver for windows

I think this is more of a issue that related to qemu. Could you please try
following QEMU repo:

https://github.com/sheepdog/qemu.git

which is rebased on latest QEMU upstream with one extra patch that deal with
qcow2 bug.
