Re: [9fans] Xen and new venti

[stella@plan9.jp]

Hi,
Frist of all a note for erik:
	>> I had a problem of type in xendat.h fixed by replacing
	>> uint8 with uint at line 1540

	>i suspect you mean uchar.  (or uvlong if they're counting
	>bytes.)
I meant uint [or so I remember] but I can't give any explanation for this

I tryed both compiling the kernel with xen 3.2.0 and xen 3.0.2 include files with the same result
I've debugging active on xen so I will paste at the end what happens
In any case it's odd that the kernels from /n/sources/xen/xen3 boots smoothly on xen 3.2.0
[without venti of course ] while the others do not.

Sorry if the following paste is not polite

S.

PS: I have no Xen 3.0.2 to test the kernel with but I'm willing to give it to anyone who does.
