Xen 4.11.2-pre - Assertion !blk->legacy_dev
Hi @all,

i have a little problem with my upgrade to Debian Buster & Xen 4.11.2 & qemu-system-x86 (1:3.1+dfsg-8+deb10u3).
When i start a windows2003.cfg file, the DomU crashed. Here is my log entry:
char device redirected to /dev/pts/12 (label serial0)
VNC server running on 127.0.0.1:9999
qemu-system-i386: /build/qemu-IqidUC/qemu-3.1+dfsg/block/block-backend.c:913: blk_get_attached_dev_id: Assertion `!blk->legacy_dev' failed.

I found a message (https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg51080.html), that this bug in 4.13 fixed.
The Problem is the "block-backend.c" (https://github.com/lf-edge/eve/blob/master/pkg/xen-tools/patches-4.12.0/01-remove-assert.patch), how i can remove this entry?
I search this day and i don?t found the block-backend.c.

Can anybody help me with this problem?

Thank you very much!!!!

The file belongs to QEMU project. You can find it by download the source
of the QEMU package.
