Commenting out the assertion in question (which has been in the source
code for the last year) seems to resolve the problem with no noticeable
negative impacts, or at least this is what my tests have shown.

Title:
assertion failed in exec.c while attempting to start a guest (latest
commit)
Status in QEMU:
New
Bug description:
Hi team,
I decided to try the latest commit on git (previously used version
1.3.0), and I got failed assertions while attempting to start my
guests:
eclipse ~ # qemu-kvm -enable-kvm -hda arch.img -m 4096 -smp sockets=1,cores=4
-vnc :0 -cpu host -vga std -net nic,model=e1000,macaddr=00:00:00:00:00:00 -net
tap,ifname=vm0 -qmp tcp:0.0.0.0:4900,server,nowait
qemu-kvm: /var/tmp/portage/app-emulation/qemu-9999/work/qemu-9999/exec.c:982:
qemu_ram_set_idstr: Assertion `!new_block->idstr[0]' failed.
Aborted
The assertion seems valid, so whatever's causing it is probably to
blame. I haven't dug around much to find out what calls the method
(qemu_ram_set_idstr()), but that is probably the best place to start.
The host contains a Xeon E3-1240 CPU, virtualising a bunch of guests
one of which is Arch Linux 64-bit, if that helps.
eclipse ~ # qemu-kvm -version
QEMU emulator version 1.4.50, Copyright (c) 2003-2008 Fabrice Bellard
It looks like this assertion happens if you call the executable
without any parameters as well:
eclipse ~ # qemu-kvm
qemu-kvm: /var/tmp/portage/app-emulation/qemu-9999/work/qemu-9999/exec.c:982:
qemu_ram_set_idstr: Assertion `!new_block->idstr[0]' failed.
Aborted
Thanks.
