[Xen-devel] Is live migrate a guest from 32bit platform to 64bit platform a supported feature?

["Zhao, Fan" <fan.zhao@xxxxxxxxx>]

Hi,

I tried to live migrate a 32bit guest from 32bit platform to 64bit platform, but met failure, so I’d like to consult that is this a supported feature?

Xend.log shows:
