Re: XenServer 6.5(SP1) - HVM 're0: watchdog timeout' errors - summary...

In the vain hope this'll help others having this issue... Having looked at this now for some time - and run a lot of tests, the current best solution to allow a FreeBSD domU under XenServer 6.5 to act as a gateway, or run OpenVPN (or dhcpd etc.) and remain agile - is to switch to VirtIO

I just read that you were working on importing a newer netfront from Linux and thought that maybe this could help finding the culprint, as KVM users seemed to have similar issues, e.g. issues with the offloading capabilities of the pv nic and/or checksum errors. Anyhow, awesome news that

I just noticed that these performance problems do not occur under 10.0 and 10.1. Starting with 10.2 IPv4 TCP performance drops from ~12 Gb/s under 10.1 to ~350 Mb/s under 10.2. Should i write a new bugreport for this? > On 09 Sep 2015, at 22:58, Sydney Meyer wrote: > >

XenServer 6.5(SP1) - HVM 're0: watchdog timeout' errors...

Hi, We have a bunch of FreeBSD 10.1 hosts we run the NIC's as HVM (this avoids a known networking issue with XenServer and PV networks under FreeBSD to do with routing packets for other Xen DomU). This seems to work OK - but recently we've had a whole bunch of: Sep 7 12:41:08 host1
