Hi, This patch series fixes the S3 resume of a domain running xenstored and a frontend over xenbus (xen-netfront in my use case). As device resume is happening before process resume, the xenbus frontend resume is hanging if xenstored is not running, thus causing a deadlock. This patch series is fixing that issue by deferring the xenbus frontend resume when we are running xenstored in that same

Hello, i''ve a xen-4.0.0-rc1 with 2.6.31.6 pv_ops. Dom0 seams to work fine. But i can only boot "old" domU kernel. A pv_ops Kernel hangs after initrd.

I am trying to get a pv_ops dom0 working for testing, but I am running into an elf_init error: (XEN) *** LOADING DOMAIN 0 *** (XEN) elf_init: not an ELF binary Full output attached. >From what I have read on the mailing lists, it seems that it is usually a problem with either grub or a corrupt dom0 kernel. Attached is my kernel config (2.6.28-rc6-tip). I followed the instructions on:

Hi, another issue I''m seeing with 3.0-rc2 and Xen is that there is an unexpectedly high amount of kernel reserved memory. I suspect that Linux allocates page table entries and corresponding data structures for the whole 6GB areas of the provided ''physical RAM map'' even though it has rather big unusable holes in it.

Did a ''git pull'' a few minutes ago and tried to rebuild my kernel and was given this error: make CHK include/linux/version.h CHK include/linux/utsrelease.h SYMLINK include/asm -> include/asm-x86 CALL scripts/checksyscalls.sh CHK include/linux/compile.h CC drivers/acpi/acpica/hwsleep.o drivers/acpi/acpica/hwsleep.c: In function

Lots of changes since v2, too much to remember or summarize. Please ignore patch 11/11, it's just for my testing. Rich.
