Hi, I have: - Linux 2.0.30 - NT 4.0 - Samba 9.16pl11 - same user name and password on Linux and NT 4.0 (user1, pwxxx) and the smb.conf of below. When I create a file on the samba share [tmp] from the NT 4.0 machine, the owner is always 'nobody' (my guest account). I can not manage it to give it my own name (user1). I can not create a file in another directory neither, because samba

If the guest OS has crashed this is going to mean QEMU waits forever and thus migration won't complete. Similarly you need to consider that the guest OS may be malicious and simply never respond. So if the migration code is going to use the guest ball...

Get the free pages information through virtio and filter out the free pages in the ram bulk stage. This can significantly reduce the total live migration time as well as network traffic.

After upgrading from xen 3.2.x to xen 3.3.0 I get an error message when using pci passthrough with pv guests (my system is not vt-d enabled): xm create -c /etc/xen/domU/myguest Using config file "/etc/xen/domU/myguest".

The current QEMU live migration implementation mark the all the guest's RAM pages as dirtied in the ram bulk stage, all these pages will be processed and that takes quit a lot of CPU cycles. >From guest's point of view, it doesn't care about the content in free pages. We can make use of this fact and skip processing the free pages in the ram bulk stage, it can save a lot CPU cycles
