After a guest is live migrated, the xen-netfront driver emits a gratuitous ARP message, so that networking hardware on the target host's subnet can take notice, and public routing to the guest is re-established. However, if the packet appears on the backend interface before the backend is added to the target host's bridge, the packet is lost, and the migrated guest's peers become

I''ve implemented code to send out bogus gratuitous ARP packet from vna in order to fix CR 6701114. The webrev is at: http://jurassic.eng/net/consulte.prc/export/build/xvm-6701114/webrev Some backgroud information (see CR 6701114 for more detail): During live migration of an xVM domain from one dom0 to another, the VNIC will be moved from one switch port to another. But, the

Hello, My apologies if this isn''t the right place to send questions about this thread. I have a couple one''s about proxy_arp and gratuitous arp reply frames. I have setup the proxy_arp parameter on a linux system (kernel 2.4.20). Now, when I start a M$-Windoze machine it complain about "...duplicated IP address...". This is a know behaviour, and the solution is

Hello, I have tested Xen live migration with HVM guests on xen 3.4.3 and 4.1.2. In both cases, the guest migrated successfully but ping from outside failed due to layer2 address-table not being updated on switch. Once the guests initiates network traffic, then pings from outside work. I''ve searched Xen mailing lists and wiki and haven''t found any definitive information about

I originally meant to post only the "vector.h" patch, but then (independently) nbdkit wouldn't build. Hence the other (rust plugin) patch.

Patches before the last are small cleanups. In the last patch I'm trying to extract / generalize an idea from Stefan Hajnoczi's review of my virtio-net driver for OVMF. Unfortunately I can't find Stefan's email on any mailing list archive (sourceforge, gmane, mail-archive etc. all have only my response), so I'll quote it here. The patch Stefan was reviewing is
