[Xen-API] [XCP 1.6 beta] PVHVM: "Xen Platform: blacklisted by host"

[Sergey Buravlev <bur@xxxxxxxx>]

Dear All,

Linux OS's (all in my case) in PVonHWM mode does not use PV drivers for 
block devices and nic's with message:
...
[    0.000000] Xen version 4.1.
[    0.000000] Xen Platform PCI: I/O protocol version 1
[    0.000000] Xen Platform: blacklisted by host
...

Two Intel platforms with E5620 and X5650 processors.
OS's to install:
Fedora 15, 2.6.43.8-1.fc15.i686.PAE,
Ubuntu 12.04 server, 3.2.0-32-generic
Ubuntu 12.10 server, 3.5.0-17-generic,
Debian 6, 2.6.32-5-amd64,
Fedora 17, 3.3.4-5.fc17.x86_64

All these kernels successfuly unplug emulated devices and use PV drivers 
on XCP 1.5 (although Ubuntu 12.10 and Fedora 17 did not found a cd-rom 
for continue intallation, but blkfront and netfront switched to PV mode 
in these kerners). So, it seems that the PVonHVM simply disabled.
The only similar situation I found at Citrix forum: 
http://forums.citrix.com/thread.jspa?threadID=315560&tstart=0, and I'm 
afraid that I do something completenly wrong. Can anybody point me to 
right direction? or is where a really bug in XCP or Xen?
Since I have not an idea what side I need looking for, I don't put any 
debug information in this post, and, of course, will give required.
Thanks!

Sergey.
