Re: request for joining group

[Peter Dinda]

I'm forwarding this to the development discussion group I mentioned. 

This doesn't have anything to do with your host OS.   I assume it's a 64 bit host, though.   It's almost certainly due to an incompatibility between the version of VT that your processor has and Palacios's vmx implementation.   We don't support all the numerous variants of VT.   Another possibility is that your BIOS has VT disabled.   If you show us the output of /proc/cpuinfo and the Palacios insmod output from dmesg, we can probably give some better guesses.

Please post further requests on the development group, which I've cced.   

A common way to use load/store send/receive is with the keyed stream store:

v3_save /dev/v3-vmX KEYED_STREAM file:/directory/to/save//in

v3_load /dev/v3-vmX KEYED_STREAM file:/directory/to/load/from

or 

v3_send /dev/v3-vmX KEYED_STREAM net:c:ip-to-connect-to:port-to-connect-to

v3_receive /dev/v3-vmX KEYED_STREAM net:a:ip-to-bind-to:port-to-bind-to

These are experimental features of this research VMM, particularly live migration.  If you want to see how they work or debug them, look in palacios/src/palacios/vmm_checkpoint.c and linux_module/iface-keyed-stream.c  

Good luck.

Peter

Hi , 

think  STORE is the location and URL is the interface for check-pointing . Correct me if I am wrong 

if it's about the check-pointing interface ;  which interface i should use for checkpointing  can it possible with the BLCR .

Hi ,

Thank you for replay 

I  realize the problem is with my machine it's  not supported EPT and unrestricted guest OS  so I tried on the machine who has support  and it worked .

Now i am trying  to use some basic functionality of live migration .

but  i am not able to understand the  how to save the VM . I am using v3_save but  i didn't understand the parameters  what is STORE and URL .

In reference manual i found that 

STORE indicates the storage engine, and the URL indicates how the storage engine is to save the data .

what storage engine it talked about
