second time do S4 guest Call Trace
Please get the entire guest call trace via serial console. Created attachment 624614 [details]
call trace log
Looks like the pm-hibernate command gets stuck wanting more RAM. I see you have passed -m 8G to the guest; how much swap space does the guest have?

I see you > have passed -m 8G to the guest; how much swap space does the guest have? in guest : # free -m total used free shared buffers cached Mem: 7744 308 7435 0 8 54 -/+ buffers/cache: 245 7498 Swap: 3967 97 3870 So you have more RAM than swap space. Increase the amount of swap space to at least the amount of RAM you have. You may need more, depending on the usage. (In reply to comment #8) > So you have more RAM than swap space.

I believe we should close it as NOTABUG then. I was going to suggest updates in the documentation, but I think it's already documented somewhere that you need enough swap to perform S4. Amit, anything else? (In reply to comment #10) > I believe we should close it as NOTABUG then.
