Hi, this version requires that host and guest have the same PAE status. NX cap is not offered to the guest, yet.

Impact: potential bugfix In theory, the kernel could reuse the same page as pgdir for a new process while the hypervisor keeps it cached. This would have undesirable results.

We still assume the Guest and Host have the same PAGE_OFFSET settings, but now we don't assume 0xC0000000.

Hi, I'm setting my lguest playing environment with qemu, but didn't have a good start... maybe because my modest laptop only has 512Mb of RAM. This is my qemu command: qemu -s -no-kqemu -m 400 -hda linux26.img -net nic,model=3Drtl8139 -net tap ( linux26.img includes a 2.6.21.5 kernel with the lguest-2.6.21-307patch= ) This is my lguest command

If we're building a pte, we can use simple assigment; only use set_pte etc. when we're actually going to use that destination as a PTE. I don't know that we'll ever run under Xen, but it's neater. And use set_pte/set_pmd rather than assuming native_ versions, even though that's probably true for most people. (Includes compile fix by Kamalesh Babulal <kamalesh at
