Reading this mail I found out that the main cause of problems on my  
OpenSolaris instalation
is probably in xenpci, because after installing PV drivers that  
disables boot of Windows with
or without /gplpv option.
With /gplpv option I get BSOD (boot device inaccessible), after Widows  
logo (with dummy progress indicator)
without /gplpv Windows just freezes on Windows logo (progress  
indicator stops running).
