Dear all
I have been trying to setup stubdomains for added security on a test machine so I could then suggest to use xen at work with some added "backbone" and practical experience.
Unfortunately I am unable to launch domains with a stubdomain when there's a NIC configured in the VM config file.
The Domain launches without problems when I comment the vif= entry.
The Error I am getting is the following:
libxl: error: libxl_dm.c:1284:stubdom_pvqemu_cb: error connecting nics devices: No such file or directory
I have tried different types as well (ioemu, etc.).
More logs/configs can be found further below.
Thank you very much in advance,
Peter

These often suggests that your xencommons initscript is not up to date and
isn't populating some of the required nodes for dom0. I'm not sure if this
would have the knock on effect of the breakage you describe, but it is
worth fixing in any case.
Given "No such file or directory" I'd also be inclined to check that
/etc/xen/scripts exists and has stuff in it, especially vif-* and that they
are executable, there #! refers to a shell which exists etc.
Weirdly our automated test test doesn't seem to include the stubdom jobs
for 4.5 (they appear to being at 4.6), but I can't see at all where such a
test is deliberately suppressed by the test code. Perhaps Wei (CC'd) knows.
FWIW the flights testing stbudom in xen-unstable use a cfg file which looks
like:
http://logs.test-lab.xenproject.org/osstest/logs/64035/test-amd64-amd64-xl-qemut-stubdom-debianhvm-amd64-xsm/merlot1---etc-xen-debianhvm.guest.osstest.cfg
It doesn't look to me to be materially very different to what you have.

4.5 has a bug that completely stops stubdom from working. Paul provided
a workaround which was backported to 4.5.1. I considered 4.5 branch
stubdom broken so I skipped that branch.

Can you try a config with vif then
xl create -p guest.cfg
And then use xl list to see if stubdom is alive?
You should see something similar to:
Name ID Mem VCPUs State Time(s)
Domain-0 0 2863 4 r----- 7041.7
wheezy-hvm 699 511 1 --p--- 0.0
wheezy-hvm-dm 700 32 1 r----- 19.9

xl create -p guest.cfg doesn't create any domains

The "(null)" here instead of "Domain 0" is another indicator that your
initscripts are not correctly up to date. In particular it appears that
"xen-init-dom0" has not been called.
How are you installing Xen? From source or from distro packages?

If I understood Wei correctly it was backported to 4.5.1 and therefore is
already in the 4.5.2 release which you are using.
Ian.

That's probably stubdom already crashed and it triggered domain
destruction.

Hmm... This is not right. Can you do xenstore-ls -f and paste in output?
Have you run xen-init-dom0?
Also xl dmesg can give some insight on whether stubdom crashes. (I see
you already have guest_loglvl=all in xen command line)

dd748d128d86996592afafea02e578cc7d4e6d42 in master branch. It should be
in 4.5.1 already, which means your 4.5.2 is OK.
Wei.

Super!
I'm sure other Arch users would appreciate it if you filed a wishlist bug
with the distro such that this "Just Works" in the future ;-)

Sorry to enter into the conversation at this late stage, but as an Arch
user myself I strongly recommend using the official wiki, it's usually
accurate and up-to-date. In this case:
https://wiki.archlinux.org/index.php/Xen#Installation_of_Xen_systemd_services
Unfortunately I couldn't have been of much help in the matter earlier
anyway since 1. I'm developing for Xen on another distro, and 2. I don't
rely on any package / system script (I have to build Xen from source).
Cheers,
Razvan
