Hi : As I want to know the information of the VMs that currently runing on the same physical machine, I''d like to get those VM''s information from xenstore, such as macaddress. Indeed, what I want is IP address, so, if guest can write things to xenstore, I''d like it write its IP address into xenstore and let domain0 reads it directly. So, can anybody tell me whether a PV

orabug: 14470382 When Dom0''s network environment change, for example the issue, DomU should send send gratuitous ARP initially to notify how to reach it. To fix the bug, we should modify backend and frontend at the same time. For fixing frontend, i filer the new bug 16182568. The review only to backend. For fixing the backend, I have 4 patch for review. Thanks, Jason

First, maintainer''s addresses (Ryan Wilson <hap9@epoch.ncsc.mil>, Chris Bookholt <hap10@epoch.ncsc.mil>) are wrong (users unknown to remote mailsystem), so posting to you: PCI bus format strings are wrong. "%04x:%02x:%02x.%d" should be used instead of "%04x:%02x:%02x.%1x" (in many places of linux+v3.2.1/drivers/xen/xen-pciback/pci_stub.c) --
