Dear xen-devel, There''s a race condition in xenfs (xenstore driver) that causes userspace utility xenstore-watch to crash. Normally, the userspace process gets an "OK" from xenfs and then the watch fires immediately after. Occasionally, this happens the other way around: the watch fires before the driver sends "OK", which con...

Is there any way for unprivileged guests to map each others memory without grant tables? Now that the pressure is off for me to support SMP internally, I''d like to switch back to using -testing.

I''ve been looking at perhaps sharing some data between various domUs. Specifically, a Gentoo Portage tree. I found XenFS (http://wiki.xensource.com/xenwiki/XenFS). Is this going anywhere?

Hi all, I''d like to know if it''s possible to have more verbose output when running a block-prefix script. Other than xend.log.

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With
