hi, I have to configure Xen server and DomU''s which should be able to talk to different vlans - depending on services put on DomU''s. I would like to enslave 2 NICs via bond interface. Both NICs are on trunk ports which are configured in the same way, the same native vlan. I don''t know, if I have to add vlans tagging to eth* interfaces then enslave tagged eth*

...y servers, namely all the ones running Centos5 When I try to download a file from the server to a machine outside our Cisco 6500 router/firewall, the download hangs about half the times (15 out of 40) when less than half a megabyte into the transfer (varied from 76 kb to 496 kb). One server has a portchannel (Cisco speak for ethernet bundle), others do not, some use e1000, some use broadcom, I've tried httpd and scp transfers, I've tried from three different clients, Here's the really annoying part: the problem only occurs when downloading from outside the firewall, not when transferring f...

...r on 10 Gbit) backbone, 1Gbit for the clients For boot, Gigabit to the client may not make too much difference but I'd get your backbone and boot/image server(s) up to 10Gbit before pushing clients up and carefully consider pushing the backbone to 2x10Gbit in some active config (EtherChannel / PortChannel / LACP / Port Trunk). Remember that depending on your balancing algorithm, you could get 1 client flooding link-A, a second client trying to use link-A and link-B being unused. > - the "standard" .iso will grow to 60MB or more I don't know any tftpd that can't handle this (a...

...down the VM or power off the VM, libvirt attempts to restore its original MAC(all-zero mac). There is no issue with this scenario. When we restart the VM, there is no attempt to restore/revert its original MAC(all zero mac). This problem leads to duplicate MAC issue on the guest (if configured with portchannel). Could you please help us in resolving the issue? Questions like this should be sent to libvirt-users@redhat.com<mailto:libvirt-users@redhat.com> rather than to an individual's email address. This makes the likelyhood of getting an answer much higher, and also creates an archive of the...

So I have this dual 16-core Opteron Dell R715 with 128G of RAM attached to a SuperMicro disk enclosure with 45 2TB Toshiba SAS drives (via two LSI 9200 controllers and MPxIO) running OpenIndiana 151a4 and I''m occasionally seeing a storm of xcalls on one of the 32 VCPUs (>100000 xcalls a second). The machine is pretty much idle, only receiving a bunch of multicast video streams and
