SEAMCALL fail upon TD termination

mmisono commented 2 months ago

I found that sometimes TD termination (poweroff in the guest) produces the following messages. dmesg.txt is the full log (the log contains multiple error messages of multiple time execution). It seems this tends to happen if TD resources are large. I repeat launch and terminate TD with 56vCPU and 256GB memory (using run_td.txt) and I get this more often than once in ten times. I am able to launch another TD after getting this message.
