Re: [Xen-devel] Xen 3.2 - 32-on-64 save/restore



Hi Keir,

Thanks for your answer.

When I usse a "xm save web-test web-test.save", xendl.log says:

After, in xm list, it shows it again as runnning, but the Time(s) grow quickly.

web-test 18 512 4 r----- 273.1

30 secondes after

web-test 18 512 4 r----- 437.0

etc...

(the virtual machine is not used for anything yet)

Trying to xm console web-test also doesn't work anymore (frozen console)

Kind regards,

Hello,

I am trying the unstable 3.2 version of Xen and would like to know
if the save/restore/migration feature is supposed to work in the current
build ?

Actually if I try to save a 32bit dom U it throws this error:

[root@xen03 /]# xm save web-test web-test.save
Error: /usr/lib64/xen/bin/xc_save 24 17 0 0 0 failed

Thanks for your answers.

Kind regards,
