I've an Opensuse 13.1 DomU on a 13.1 Dom0.

Both host & guest were upgraded from 12.3.

The Opensuse 13.1 Xen DomU Guest is booting successfully, but taking a
long time (~3 mins; up from ~20sec on 12.3).

Where the delay is is clear; here's img output from "systemd-analyze
plot" -> http://pbrd.co/17UxVRS

which corresponds to:

WHY, the delay is occurring, isn't clear.  Here's `journalctl -xb` ->
http://pastebin.com/YGjAMnaP (~ 1700 lines).

@ #systemd, this is called out as a possible problem:

        Nov 25 10:45:31 os131guest systemd[1]: Job
        dev-xvc-1.device/start finished, result=timeout
        Nov 25 10:45:31 os131guest systemd[1]: Timed out waiting for
        device dev-xvc-1.device.
        Nov 25 10:45:31 os131guest systemd[1]: Job
        [email protected]/start finished, result=dependency

The .cfg @ Dom0 that launches this Guest contains my usual:

        cat os131test.cfg
                name         = 'template'
                builder      = 'linux'
                bootloader    = 'pygrub'
                bootargs      = ''
                disk         = [
                
'phy:/dev/VG0/vm_os131boot,xvda,w','phy:/dev/VG0/vm_os131swap,xvdb,w','phy:/dev/VG0/vm_os131root,xvdc,w',]
                root         = '/dev/xvdc1'
                extra        = 'textmode=1 xencons=xvc0 noirqdebug
                elevator=noop'
                localtime    = 0
                on_shutdown  = 'destroy'
                on_reboot    = 'restart'
                on_crash     = 'destroy'
                ...

There are additional delays/stalls you can see in the log.

Atm, I'm only seeing these boot-up delays on Xen Guests.  Dom0 has no
similar delays, neither do any non-Xen machines.

So, something unique to the Guest -- whether it's Xen related, or other,
not clear yet.

Does anything in logs stand out?
