Re: [Xen-devel] HVM hypercalls

[Ruslan Nikolaev <nruslan_devel@xxxxxxxxx>]

I've just tried to configure newever version (2.6.32.16) from repositary. 
However, boot fails because no root device is found. I am using disk image (the 
line in HVM config is disk = [ 'file:/home/ruslan/fs1.img,hda,w' ])
I also tried to compile kernel with 'blktap' driver which is disabled in 
default kernel config, but it does not help.

The previous version (2.6.31.13) worked fine with the same disk image and 
default configuration.

Thanks,
Ruslan.
