5be12f8459 qmemman: switch off memory balancing when doing xm save 
Apparently, it interferes:
INFO (XendCheckpoint:417) ERROR Internal error: Could not get vcpu context
INFO (XendCheckpoint:417) ERROR Internal error: Failed to map/save the p2m frame list

22df517425 qmemman: detect domain list change by watching /vm, not /local/domain 
The latter triggers on every memory/meminfo key update, which needlessly
adds xenstore requests.

10408d61db qmemman: when low on memory, do not make a VM go below prefmem 
Now the balance() has two different cases: enough memory and low_on_memory.
In the former, distribute memory proportianally; in the former, dont do this, as this
makes a VM go below prefmem.

c66e0848f3 qmemman: limit domain memory to 2G to workaround for xen xml-rpc limitation 
File "/usr/lib64/python2.6/xmlrpclib.py", line 710, in dump_int
    raise OverflowError, "int exceeds XML-RPC limits"
OverflowError: int exceeds XML-RPC limits
How crappy.

de2619fbed qmemman: wrap xenapi.memset within try/except 
It can fail e.g. when a domain is being shutdown with a pretty
message like
 File "/usr/lib64/python2.6/site-packages/xen/xend/XendDomainInfo.py", line 1322, in setMemoryTarget
    (target * 1024))
Error: (1, 'Operation not permitted')

eb6755e93c qmemman: fix locking 
We want balance() to wait on a lock even after balloon() has finished,
until socket client has closed.

4cf0a61858 Before restoring DVM, check for available xen memory 
As we already do xm mem-set 0 800 in qubes_core, this is a
correct check. Now, there should be no errors from qubes_restore
in normal circumstances.

11b8a0409f DVM: execute user script before save 
qubes_prepare_saved_domain.sh now takes optional second argument, the
filename. The content of the file will be copied (via xenstore) to DVM
and executed just before save. This makes it possible to preload memory
with useful apps.

0c0f34ba9b DVM: manage savefiles 
Instead of hardcoded savefile name, use a symlink in
/var/run/qubes. Tools should set this symlink to a correct
savefile. Also, test whether the savefile is older than the
template root.img.

c8ef500588 Pause/Unpause all running VMs on system suspend/resume 
This is to fix the VM lockup problem on HT processors that
occured after S3 resume (see ticket #52).

The qvm-run command now takes additional two switches:
--pause
--unpause

115df6f1af Dom0: sync wallclocks in all vms upon resume from S3 sleep 
This is really a workaround, until Xen implements proper suspend/resume
mechanism for notfying DomUs about system-wide S3 sleep.
