Hi, all
We met an issue while doing the nbd related test, will you please help to review if this issue is a bug? Thank you!
=================================================
Subject: [s3-bug-review] [RHEL7] [Virtual disks] Met error messages while the guest OS booting up on a nbd device.
Description:
Start a guest with only one nbd device and with a linux OS installed on the nbd device,
"virsh create" return successfully, but meet error messages while the guest OS booting up.
Version:
libvirt-client-1.1.1-29.el7.x86_64
qemu-kvm-1.5.3-60.el7.x86_64
kernel-3.10.0-121.el7.x86_64
How reproducible:
100%
Steps to Reproduce:
1. start nbd server on the server host.
#nbd-server 10809 /var/lib/libvirt/images/r7g-qcow2.img
2. create a domain with xml as bellow.
# virsh create r7g-nbd.xml
Domain r7g-qcow2 created from r7g-nbd.xml
# virsh dumpxml r7g-qcow2| grep disk -A 7
<disk type='network' device='disk'>
<driver name='qemu' type='qcow2'/>
<source protocol='nbd'>
<host name='10.66.106.34' port='10809'/>
</source>
<target dev='sda' bus='scsi'/>
<alias name='scsi0-0-0-0'/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
# ps -ef| grep qemu-kvm| grep nbd
qemu 15724 1 99 09:58 ? 00:00:47 /usr/libexec/qemu-kvm -name r7g-qcow2
......
-drive file=nbd:10.66.106.34:10809,if=none,id=drive-scsi0-0-0-0,format=qcow2
-device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=1
......
3. login to the guest, the console output error messages and fail to booting up.
Actual results：
As described.
Expected results:
The guest can boot up successfully.
Additional info:
Attached screen-shot and log files.
