Bug 670420

Description of problem:
In F14, when the host is rebooted, kvm guests are hibernated using /etc/init.d/libvirt-guests. The problem is that after resuming them again, their system time is not updated. The virtual rtc inside the guest is correct (according to hwclock(8)), but the system time according to date(1) is back with the time difference being the time during which the guest has been suspended.

I think the guest should be informed that it has just been resumed, and it should update its system time from the virtual rtc (and possibly do other things like renew its DHCP leases, etc.).

Apparently VMware can pass such an information to the guest using their vmware-tools.

Version-Release number of selected component (if applicable):

libvirt-0.8.3-2.fc14.x86_64
libvirt-client-0.8.3-2.fc14.x86_64
qemu-system-x86-0.13.0-1.fc14.x86_64
kernel-2.6.35.10-74.fc14.x86_64

How reproducible:
100 %

Steps to Reproduce:
1. Install F14 with libvirt and libvirt-client packages
2. Create a new VM, install F14 to it
3. Shutdown -h the host system
4. Wait several minutes and start the host system again
5. Log in to the guest system and run "hwclock" and "date"
  
Actual results:
The time of hwclock and date differs, and the difference equals to the host downtime (or guest suspend time).

Expected results:
After being resumed, guest should update its system time.


Additional info:
I am filling this under kvm, but I am not sure on which level the resume notification should be sent.
