[Xen-users] saving a driver domain

["Masroor Vettuparambil" <Masroor.Vettuparambil@xxxxxxxxxxxx>]

Hello,

 

Is it possible to save a driver domain(with pass-through enabled)?

 

I got the following error when tried to save it (xen v3.1.0).

 

[2008-02-05 20:05:21 3900] INFO (XendCheckpoint:349) Saving memory pages: iter 1  69%ERROR Internal error: Fatal PT race (pfn d94, type 10000000)

Traceback (most recent call last):

    forkHelper(cmd, fd, saveInputHandler, False)

    raise XendError("%s failed" % string.join(cmd))
XendError: /usr/lib64/xen/bin/xc_save 23 3 0 0 0 failed
[2008-02-05 20:05:21 3900] DEBUG (XendDomainInfo:1699) XendDomainInfo.resumeDomain(3)

 

I checked the free memory available during saving and it has enough memory there.

 

without pass-through migration is working well on the same environment.

 

regards

Masroor
