[Xen-devel] [PATCH] PAE shadow (log-dirty guest-refcount)
Attached patch allows PAE xenlinux to run in the shadow mode using log-dirty guest-refcount, which is required to support save/restore/relocate. We can turn on/off the mode every 5-sec interval while doing kernel build (make -j4), for example, and it survives for hours. We are still restoring log-dirty mode for x86_64 xenlinux, which is not very stable right now, but I believe it should be done very soon. We also checked that it did not break 64-bit VMX domains, which uses different sub-mode of the shadow mode.
