[Qemu-devel] [Bug 1191606] [NEW] qemu crashes with iscsi initiator (libiscsi) when using virtio

[Klaus Hochlehnert]

Public bug reported:

I just tested qemu (with kvm) with an iscsi disk using libiscsi.

I tried to install Ubuntu 12.04 as guest and when it comes to the disk
configuration during the installation qemu crashes without any notice.
No log, no dump.

In the log of the iscsi-target I found this:
iscsi-scst: ***ERROR***: Connection with initiator 
iqn.2013-06.de.test:testsrv01 unexpectedly closed!

qemu version 1.5.0
libiscsi version 1.9.0
Host OS: Ubuntu 12.04 with 13.04-Kernel (3.8)
iSCSI-target: SCST 2.2.x

qemu command line:
/usr/bin/kvm ... -drive 
file=iscsi://192.168.x.x/iqn.2006-10.de.test:test/0,if=virtio,bus=0,unit=0,cache=none,media=disk,aio=native
 -iscsi initiator-name=iqn.2013-06.de.test:testsrv01,header-digest=CRC32C-NONE 
...

When choosing IDE instead of VIRTIO it doesn't crash when scanning the
disks...
