Description Mike Cao 2010-05-20 02:57:37 UTC
Description of problem:
VM can not start with virtual blocks.

Version-Release number of selected component (if applicable):
# uname -r
2.6.32-25.el6.x86_64
# rpm -q qemu-kvm
qemu-kvm-0.12.1.2-2.56.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1.start a vm by using following command:
usr/libexec/qemu-kvm -rtc-td-hack -bt hci,vlan=0 -no-hpet -usbdevice tablet -drive file=/RHEL-Server-6.0-64.raw,if=ide,format=raw -net nic,macaddr=20:10:43:23:33:42,model=e1000,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -uuid `uuidgen` -vnc :5 -boot dc -cpu qemu64,+sse2 -smp 2 -m 2G -monitor stdio -balloon none -startdate now
"qemu: could not open disk image /RHEL-Server-6.0-64.raw: Success"

2.start a vm by using following command:
# #/usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -drive file=RHEL-Server-5.5-64-virtio.qcow2,media=disk,if=none,id=test -device ide-drive,drive=test -uuid `uuidgen` -vnc :5 -cpu qemu64,+sse2 -smp 2 -m 2G -monitor stdio -balloon none -boot c
qemu: could not open disk image RHEL-Server-5.5-64-virtio.qcow2: Invalid argument

  
Actual results:


Expected results:
the VM can start successfully.

Additional info:
DownGrade the qemu-kvm to qemu-kvm-0.12.1.2-2.55.el6.x86_64
Start the VM with same command .the VM can start successfully.
It is a regression bug.

Comment 3 Mike Cao 2010-05-21 01:40:42 UTC
Retest from qemu-kvm-0.12.1.2-2.57.el6.x86_64 to qemu-kvm-0.12.1.2-2.60.el6.x86_64,with the same images by using the same commandline.

Still hit this issue.

Comment 5 Dor Laor 2010-05-24 07:40:07 UTC
I suspect you have the wrong parameters. Try without format=raw.
Also we only support cache=none.

start VM in qemu-kvm-0.12.1.2-2.56.el6.x86_64.
CLI:/usr/libexec/qemu-kvm -rtc-td-hack -no-hpet -usbdevice tablet -drive file=/home/RHEL-Server-5.5-64-virtio.raw,if=virtio,cache=none,boot=on -net nic,macaddr=20:10:43:23:33:42,model=e1000,vlan=0 -net tap,script=/etc/qemu-ifup,vlan=0 -uuid `uuidgen` -vnc :5 -boot dc -cpu qemu64,+sse2 -smp 2 -m 2G -monitor stdio -balloon none -startdate now

Expected Results:
the vm can not start. Error msg:
qemu: could not open disk image /home/RHEL-Server-5.5-64-virtio.raw: Success

Start VM with same command in qemu-kvm-0.12.1.2-2.55.el6.x86_64.the VM can start successfully.

Comment 7 Dor Laor 2010-05-24 11:01:40 UTC
Kevin, any hints?

Comment 8 Juan Quintela 2010-05-24 11:13:07 UTC
Patch sent to the list.

"raw" image format/protocol was split into "raw" protocol and "file" image.  But we didn't changed the block whitelist.

I will use this bugzilla instead of a change to the bugzilla that introduced the regression.
