Description Jeremy Katz 2006-07-25 16:29:51 UTC 
Creation of guests (both PV and FV) fails with all 2.6.18-rcX based Xen kernels
(2.6.17-1.2439.fc6xen is the one currently on my test box)

The guest creation gives an "Error creating guest OS".  Looking in xm dmesg, the
reason is related to
  (XEN) DOM0: (file=mm.c, line=822) PAE L3 3rd slot is empty
  (XEN) DOM0: (file=mm.c, line=1053) Failure in alloc_l3_table: entry 4
  (XEN) DOM0: (file=mm.c, line=1732) Error while validating mfn e1d4 (pfn 2b5bf)
for type 60000000: caf=80000002 taf=60000001
  (XEN) DOM0: (file=mm.c, line=2004) Error while pinning mfn e1d4
Comment 1 Jeremy Katz 2006-07-25 18:05:24 UTC 
Building a HV from unstable with pae=y debug=n verbose=n doesn't help this
(although there isn't helpful spew about the problem anymore and I had to hack
up libxenguest to figure out why the guest creation was failing)
Comment 2 Mark McLoughlin 2006-07-27 10:15:19 UTC 
See #200004 - the patch there could well fix this too, there's nothing arch
specific about the problem causing #200004

This is better with 2462
