This is today's nightly testing report; two new issue found and one old issue got fixed.
Due to bug 1221 listed below, testing on PAE host is blocked.
New issues:

1. Fail to create any HVM guest on IA32PAE host
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1221
2. Dom0 hangs at booting if loglvl and guest_loglvl are set as all.

Fixed issue:
==============================================
1. Xen HV hangs at booting on 32PAE host if vtd is enabled.

1. Fail to create any HVM guest on IA32PAE host
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1221
Looks like it is due to Kevin Wolf's changeset 17499. Your attempt to go back to older tools obviously didn't work -- the backtrace in xend.log comes from a line introduced by c/s 17499.

2. Dom0 hangs at booting if loglvl and
guest_loglvlare set as all.
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1222
Well, the obvious answer is to print less drivel in the VT-d code. There's no reason at all to print so much useless text, even in a debug build.
Actually a second point is that we should drop characters from the 16kB serial buffer rather than spin in the hypervisor waiting for the buffer to empty. I'll implement that.

I reverted this changeset.

I greatly reduced printk() count in vtd code. If this stuff was useful for debugging (which for the most part it probably wasn't) you might add it back via an ifdef'ed debug macro.

This is now done.

Create the directory /var/run/tap if it doesn't exist yet. Try to continue even if the blktap communication pipes couldn't be created. The VM might not need tap:ioemu and run just fine.
