In the past I hacked around a problem with the order of starting (and with several bugs) a network stack combined of network bonding (teaming) + VLAN tagging, and then with network bridging (aka – Xen bridges). This kind of setup is very useful for introducing VLAN networks to guest VMs. This works well on…
This sounds weird, but I have witnessed it today, and had to work rather hard to figure the cause of the problem. When using ” Intel Corporation 82575EB Gigabit Network Connection (rev 02)” (as lspci reports), TCP offload causes problems. Symptoms: The host can communicate with the guest flawlessly (including HTTP get for larger than…
