We have been performance testing SLES 12 Xen. In addition to SLES vm's, we are also testing Windows Server 2008 R2 x64 and Windows 7 Pro x64 (with the VMDP 2.2). We have recently run into an issue with networking. Section 19.1 of the SLES12 Virtualization guide notes that dom0 bridges created through YAST are supported and can to be used with domu's through virt-manager and virt-install. This appears to be the same functionality we had in SLES 11 SP3 dom0's, however, when testing newly created, fully virtualized Windows hosts, the Windows VM's are fine except there is no network traffic (even with all firewalls disabled). Is SLES 12's YAST really setup to manage network bridges as required for Xen 4.4.x domu/dom0?
