Description Artyom 2014-06-26 08:30:14 UTC
Description of problem:
When I start vm in paused mode(not important via run once or just added flag via edit window) and after it stop vm(without start it) pending_vmem_size on host stay with value of vm memory guaranteed memory, if you again start vm in paused mode it will add another bunch of memory to this value(1024+1024), so you can reach state when you don't have running vms on host, but also can't start new vm because memory filter 

Version-Release number of selected component (if applicable):
av10

How reproducible:
always

Steps to Reproduce:
1. create new vm with some guaranteed memory(1024)
2. Run it in paused mode, wait until vm status paused, stop vm
3. Check pending_vmem_size of host, via engine database(select pending_vmem_size from vds_dynamic where vds_id='your_host_id';)

Actual results:
1024

Expected results:
0

The same thing happening when you migrate paused vm, so if you migrate vm from host to host you just increase pending_vmem_size parameter of each host
