Hi, i wont separate drbd traffic in domU to eth1 interface. What is the best way to do that? I think about make eth1 nic passthrough to my domU. Can i expect some problems with this configuration? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Why are you using drbd in domU instead of dom0?

ganeti is for hw fail over and not solve auto fail over. I have 2 physical xen servers on xen1 is ha1-mysql vm and on xen2 is ha2-mysql. Bouth vm share virtual ip and drbd disk where is mysql db. If one of them is down (if vm have some issue or physical server go down) second take over ip and mysql service. ______________________________________________________________> Od: mark@campbell-lange.net > Komu: "<s3t@centrum.sk>" <s3t@centrum.sk> > CC: xen-users <xen-users@lists.xensource.com> > Datum: 31.10.2010 20:28 > Předmět: Re: [Xen-users] dedicate nic to drbd in domU > >For HA you want drbd in your dom0.

right, now i try multiple bridge configuration works ok. Question was if is pci passthrough stable or i can expect some trouble with this configuration. I need use this model in production and i don''t know witch way is more stable :) ______________________________________________________________> Od: mark@campbell-lange.net > Komu: Mark Adams <mark@campbell-lange.net> > CC: "<s3t@centrum.sk>" <s3t@centrum.sk>,xen-users <xen-users@lists.xensource.com> > Datum: 31.10.2010 21:28 > Předmět: Re: [Xen-users] dedicate nic to drbd in domU > >Anyway, for a dedicated nic in domU you can use pci passthrough or a custom network script.

Personally I''ve had some OK success with HVM passthrough (VT-d), but issues with PV. Didn''t get to the bottom of my problems. Other people report it works perfectly fine! If using multiple bridges work OK I would suggest this is the easiest and most stable way forward.
