Xen project Mailing List

Well today, I compiled jeremy kernel 2.6.32.27 on DOMU and followed the steps given in the previous mail. First allocated hugepages and then written on them using C-Code from previous mail. But this time DomU didn't crashed but the terminal got handed.
I again checked dmesg but still there was no change at all. Even I put printk at few part of code which I found from the crashdump of the crashed kernel but still these printks were not reachable.

I think that jermey kernel must have handled this case but still its buggy as terminal is getting hanged.

I am very much interested in doing this project for supporting hugepages in PV-DOMU
.I found few of the work done by Dave McCracken. Lets see,waiting for his reply.

Look at the PVOPS Wiki and also build the Xen hypervisor with debug enabled.

Soon will send the results.
