Subject: xen 4.10.0: stubdomain for HVM guest fails to start unless qdisk backend is used?
Date: Fri, 09 Mar 2018 07:24:51 -0800 [thread overview]
Message-ID: <87po4db7b0.fsf@prgmr.com> (raw)
I recently made a build of xen 4.10.0 and installed it.
I have a pre-existing HVM guest that uses the following configuration:
1 hard drive using the phy disk backend. The guest also uses a device
model stubdomain. After upgrading, it refuses to start, due to a
stubdomain timeout:
Parsing config from somedomain
libxl: error: libxl_dm.c:2203:stubdom_xswait_cb: Domain 32:Stubdom 33 for 32 startup: startup timed out
libxl: error: libxl_create.c:1538:domcreate_devmodel_started: Domain 32:device model did not start: -9
libxl: error: libxl_domain.c:1000:libxl__destroy_domid: Domain 32:Non-existant domain
libxl: error: libxl_domain.c:959:domain_destroy_callback: Domain 32:Unable to destroy guest
libxl: error: libxl_domain.c:886:domain_destroy_cb: Domain 32:Destruction of domain failed
There is nothing in the logs.
I noticed that a similar guest was booting with no issue. The
difference was that the booting guest also had a CD-ROM attached. That
CD-ROM used the qdisk backend, because it is backed by an ISO9660 image file.
I changed the disk parameter in the first non-booting guest so that it
used the qdisk backend rather than phy, and it booted with no trouble.
Has anyone else had an issue like this after upgrading to 4.10? I did
some searching, and I didn't find anything. I'm a bit surprised by
that. Since this is so easy for me to reproduce, and no one else has
mentioned it, I wonder if my build could be subtly broken somehow.
