Subject: [Qemu-devel] [Question] dump memory when host pci device is used by guest
Date: Fri, 07 Oct 2011 17:46:57 +0800 [thread overview]
Message-ID: <4E8ECA91.8040409@cn.fujitsu.com> (raw)
Currently, virsh dump uses monitor command migrate to dump guest's memory
to file, and we can use crash to analyze the file.
Unfortunately, virsh dump can not work if guest uses host pci device. The
reason is that the device's status is also needed to migrate to remote machine,
and the host pci device's status is not stored in qemu. So it is unmigratable.
I think we can we can add a option to qmp command migrate(eg: skip) to allow
the user to skip the check, and this option should be used only when dumping
the guest's memory.
Thanks
Wen Congyang
