When setting e.g. 'on_crash=rename-restart' option in domain config
and crashing guest OS running in the domain, the new domain is
restarted with same name as renamed domain.
jfehlig4: # xm li
Name ID Mem VCPUs State Time(s)
Domain-0 0 1233 4 r----- 937.9
Domain-e64b12a0-0493-44d7-afde-55c776513426 21 384 1 ---c- 14.3
Domain-e64b12a0-0493-44d7-afde-55c776513426 22 384 1 r----- 7.3
This patch copies the domain info prior to setting new name and uuid
in the crashed domain info and uses the copied domain info to
construct the restarted domain.

x86: Fix host S3.
Time zone info just needs to be calculated in S3 suspend procedure.
However, time_suspend() is also called on AP. That wasteful
get_cmos_time() on AP may break __cpu_die() assumption since
get_cmos_time() can take up to one second. This fix just limits it to
running on the BSP.

vt-d: Do FLR of assigned devices with VT-d
Currently there is a pdev_flr() function to do FLR before device

What's more, should do FLR before assignment and deassignment for
keeping correct device status. If the device doesn't have FLR
capablility, this patch implemented to enter D3hot and return to D0 to
do FLR. And exposed pdev_flr() in VT-d utils, then it can be invoked
by assignment and deassignment functions.

ioemu: handle empty vnc passwd
Have xenstore_read_vncpasswd return -1 when it is unable to read the
passwd from XenStore (and store an empty password). However, don't
exit in such case since it may just mean that the use didn't set a

hvm, ioemu: Fix the ide/cdrom emulation error on FC7 guest.
The new libata-eh in the Linux kernel is throwing a fit over the QEMU
cdrom device for two reasons:
1) DRQ can be set with ERR_STAT set. This is a violation of the ATAPI
state machine.
2) After a TEST_UNIT_READY ATAPI command is sent ERR_STAT is getting
set
which is correct. But, when the OS issues another ATAPI command
ERR_STAT is still set. Which is bad since the next expected command
from the OS is REQUEST_SENSE to find out why ERR_STAT is set.
