Re: Xen PV Networking issue - disable PV NIC in XENHVM FreeBSD?
On 08/02/14 16:03, Karl Pielorz wrote: Hi, I've got an 'issue' (more with Xen than FreeBSD) - the upshot is, I need to disable the PV NIC (xn) from a VM running XENHVM kernel. Is this possible? - In an ideal world I'd like to keep the storage drivers etc. - I just need to use the HVM 're' interface, not 'xn' interface... For those who want to know what the issue is - we have a number of VM's on 1 Xen machine (e.g. 'Xen1') all using PV drivers (Windows and FreeBSD VM's). A FreeBSD VM is the 'default' gateway for the others - and it doesn't work :( Packets are either going missing - or getting mangled. If you 'migrate' one of those hosts to another Xen machine in the pool (e.g. Xen2) it works. If you migrate the default gateway VM over to the other Xen machine - all the other VM's on the original XenServer suddenly work (i.e. can see the outside world) - alternatively if you switch from PV drivers to HVM drivers on the affected guests - everything works, regardless of whether the VM's are on Xen1, Xen2 - or the same XenServer as the default gateway VM. Only PV - PV shows the issue, and only when they're both hosted on the same XenServer. Hence wondering about disabling the PV nic on the default gateway, instead of having to do it on all the other VM's... That's quite weird... Do you see any messages in the Xen console (xl dmesg)? Can you boot with a hypervisor compiled with debug=y and see if there are any strange messages on the Xen console? Also, does replacing the FreeBSD gateway VM with a Linux PV VM solve the issue? (ie. just to check if Linux also shows this behaviour) Roger. ___ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to freebsd-xen-unsubscr...@freebsd.org
