I've got a really strange problem running Xenserver 7.0 (tried 7.1 as well) on a Dell M620 with BCM57810 network card.

The whole setup is fine and running flawlessly with no traffic. I've got a Windows Server 2016 running and can access it with RDC through a Vyos firewall etc. On another virtual machine I want to run an owncloud instance and add another IP to the network interface and forward the traffic to it. As soon as I access the owncloud http interface, the whole server is crashing with a kernel panic and error messages relating to the Broadcom network driver.

Unfortunately I cannot install the vendor driver since I don't have the kernel headers to compile the driver manually.

I tried to disable virtual interfaces in the NIC configuration but without any success. Also disable_tpa or other module parameter didn't give me any success.

Hope anyone has any ideas.

I've recently had the same trouble with Xenserver 7.1 and Ubuntu VM

Server Dell R730

NIC Broadcom Limited NetXtreme II BCM57800 1/10 Gigabit Ethernet (rev 10)

In my case the trouble was in the vlan handling.

When I tried to handle Vlan on Xen and connect 4 virtual nic's with selected Vlan's from Xenserver to a VM - the whole hardware server had repeatedly crashed 7-10 minutes after starting this VM.

A workaround was to pass the whole eth0 interface to VM, and after that to handle Vlan's inside the VM itself (eth0.100, eth0.200 etc)
