Thanks a lot for sharing this; I tried your above snippet with the
Debian Hurd img file, and it worked! Out of curiosity, how do you use
Spice with the above? It'd need a Spice-enabled viewer such as
virt-manager right? How do you point virt-manager to the VM instance
spawned with QEMU?
So it's not a QEMU bug. I'm also
running a childhurd VM and it indeed works there. The command the
childhurd service uses is:
--8<---------------cut here---------------start------------->8---
qemu-system-i386 -m 512 --device rtl8139,netdev=net0 --netdev
user,id=net0,hostfwd=tcp:127.0.0.1:11004-:1004,hostfwd=tcp:127.0.0.1:10022-:2222,hostfwd=tcp:127.0.0.1:15900-:5900
--snapshot --hda /gnu/store/84881fwqhwl37n7gbh8lhg3i01sxrp2p-disk-image
--no-reboot --enable-kvm
--8<---------------cut here---------------end--------------->8---
Stealing its --device and --netdev options applied to my case:
--8<---------------cut here---------------start------------->8---
/gnu/store/kkwyzm7b6mg42sm5cljlqrca9f5hqmyn-run-vm.sh --device
rtl8139,netdev=net0 --netdev user,id=net0,hostfwd=tcp:127.0.0.1:3333-:22
--8<---------------cut here---------------end--------------->8---
And try to connect to SSH, I can see messages like:
--8<---------------cut here---------------start------------->8---
qemu-system-x86_64: Slirp: Failed to send packet, ret: -1
--8<---------------cut here---------------end--------------->8---
So at this point I'm guessing my minimal OS declaration is too minimal
and missing a networking component. It's this:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu services ssh)
(gnu system)
(gnu tests))
(simple-operating-system
(service openssh-service-type
(openssh-configuration
(permit-root-login #t)
(allow-empty-passwords? #t)
(log-level 'debug))))
--8<---------------cut here---------------end--------------->8---
Adding the DHCP client service like so:
--8<---------------cut here---------------start------------->8---
(use-modules (gnu services networking)
(gnu services ssh)
(gnu system)
(gnu tests))
(simple-operating-system
(service dhcp-client-service-type)
(service openssh-service-type
(openssh-configuration
(permit-root-login #t)
(allow-empty-passwords? #t)
(log-level 'debug))))
--8<---------------cut here---------------end--------------->8---
I've added a note to document this and spare others the trouble of going
down this hole with commit b9ac7d9aaaa5849cc3c2acd4b1b41acdd545e66b.
Thanks a lot for helping me see the solution!
Closing.
Maxim
