Re: [Qemu-devel] Strange/wrong behavior with iSCSI Tape devices in QEMU 2.8.0-rc4

[Holger Schranz]

Hi Paolo,

thanks for the hint. In the SLES11 SP4 documentation
virtio-scsi is implemented, but this described SLES11SP4
as a host system not as a VM guest.

I'm totally confused. Why does the guest VM's runs until
version 2.7.0 without any problems (with older and newer
kernel versions)?

May be we have clear the configuration:
The host system we use is a SUSE LEAP 42.2. together with QEMU
2.8.0.

The guest systems are SLES10 - SLES12, RH 2.6.32-504 el6 up to 7.2,
and a lot of others (Debian, Fedora, ...).

Best regards

Holger
