[Xen-users] ioemu in config file and O_DIRECT option

["trilok nuwal" <tc.nuwal@xxxxxxxxx>]

In config file,  'type=ioemu' is added with vif .  Does it make the difference if we don't add.
Because i did not notice any difference in para as well as full virtulization.
Same as in case of exporting the disk to Guest dom. Is it just a placeholder or else ?

Second thing, I am running RHEL3 as a HVM DomU on xen-3.0.4. 
Every thing works fine, but i had a problem to write a file opened with
O_DIRECT  option. 
Does it supports all file IO options ( O_DIRECT etc. )  that RHEL3
supports as normal or does it depends on the drivers, that only for a
set of drivers is supports 
all IO options or something we have to configure in DomU.

Thanks,
--Trilok
