[Xen-devel] Daily Xen-HVM Builds
changeset: 8830:fcc833cbaf82
tag: tip
user: kaf24@xxxxxxxxxxxxxxxxxxxx
date: Mon Feb 13 10:41:23 2006 +0100
summary: Return real error code from Xen /dev/mem, not EAGAIN.
x460:
x86_32:
Status:
- dom0 boots fine
- xend loads fine
- single HVM domain loads fine
- Multiple HVM domains load fine
- destruction of any HVM domain causes dom0 to reboot
Issues affecting HVM:
* (same issue) During xm-test, dom0 reboots. This happens during
"11_create_concurrent_pos" test case. The destroy call is causing the
reboot.
Details:
dom0 will also reboot with the following console messages:
