This is my /tmp/qemu-smb.28665-0/log.smbd from the last attempt:

I'm reasonably sure I'm using the right binary.
smb.conf written by qemu:
,----
> cat /tmp/qemu-smb.31280-0/smb.conf
[global]
private dir=/tmp/qemu-smb.31280-0
smb ports=0
socket address=127.0.0.1
pid directory=/tmp/qemu-smb.31280-0
lock directory=/tmp/qemu-smb.31280-0
log file=/tmp/qemu-smb.31280-0/log.smbd

But I had an old qemu-kvm package (1.0) ;-) Just upgraded to qemu-kvm
1.1.0+dfsg-1 and I get the following result:
,----
> kvm -snapshot -drive file=$HOME/foo.qed,if=virtio -net
> user,smb=$HOME/tmp/myshare -net nic,model=virtio -m 2048 -cpu host -smp 2
kvm: symbol lookup error: kvm: undefined symbol: rbd_aio_discard
`----
Upgrading librbd and librados2 to 0.48-1 solves that problem.
And I also can access the smb share \o/
Looks like this bug is invalid, but leads to a couple of questions:
- I guess qemu-kvm 1.1.0 should depend on librbd 0.48-1 which is an
entirely different bug.
- It seems I forgot to upgrade qemu-kvm to 1.1.0 as well. Would it be
useful to require matching/identical versions for all the qemu-*
Packages?
Kind regards
Friedel
