| 02:28 | <PosixJumbo11234:#xen> | My question is this: is there support for checkpointing in live migration in Xen ? |
| 02:29 | <PosixJumbo11234:#xen> | I tried to see "man xm" |
| 02:29 | <PosixJumbo11234:#xen> | but there is no checkpointing there |
| 02:29 | <PosixJumbo11234:#xen> | and I have xen-3.1.0-13 |

| 09:29 | <jerkface:#xen> | hi guys, do any of you know why the I/O writes for a virtual nic would be only 2000k/sec? Yet reads use the full bandwidth? |

| 10:26 | <xdanx77:#xen> | Hello. |
| 10:27 | <xdanx77:#xen> | Is there a way to find out (in a Domain-0) how much physically memory the "real" machine has ? |
| 10:29 | <Wordy:#xen> | dmesg |
| 10:30 | <Wordy:#xen> | this a box with 8GB: |
| 10:30 | <Wordy:#xen> | $ dmesg | grep -i mem |
| 10:30 | <Wordy:#xen> | 7264MB HIGHMEM available. |
| 10:30 | <Wordy:#xen> | 727MB LOWMEM available. |
| 10:31 | <xdanx77:#xen> | hm.allready tried this but this doesn't work here.(16 gb ...) it only show the value if provied for dom0 with the boot paramter |
| 10:31 | <xdanx77:#xen> | here : 512 KB |

| 10:40 | <danpb:#xen> | hmm, xdanx77 left... for future reference 'xm info' or 'virsh nodeinfo' tell you physical RAM regardless of Dom0 allocation |
| 10:41 | <murb:#xen> | danpb: assuming no bios/grub bugs. |
| 10:42 | <danpb:#xen> | murb: sure, but you're screwed anyway then |
| 10:42 | <murb:#xen> | danpb: well i have a patched grub on one of my rented machines for this purpose.. |
| 10:44 | <danpb:#xen> | murb: my point was that those commands get the physical RAM info from the hypervisor - so if they're wrong, then so is the HV's view - so its pretty much irrelevant - they report the effective physical RAM Xen has |
| 10:44 | <murb:#xen> | dmidecode can be a useful cross check. |
| 10:45 | <murb:#xen> | if you think what xen reports is wrong. |

| 19:57 | <moemoe:#xen> | hi - i have a very strange problem (using a box with debian etch): from one moment to another, the domUs were no more reachable. |
| 19:57 | -!- | fuzzy [~fuzzy@65-127-11-19.dia.static.qwest.net] has joined #xen |
| 19:58 | <moemoe:#xen> | so I tried to find the problem - the bridge is set up correctly, the macs are fine, etc. when trying to ping a domU from inside the dom0, it doesn't work - the arp requests don't get answered |
| 19:59 | <moemoe:#xen> | so i started tcpdump - on dom0:vif1.11 i can see the arp requests. on domU:eth1, no packets arrive |
| 20:00 | <moemoe:#xen> | iptables and everything are set to defailt-policy: accept. and i have no idea left what i could check or do |

| 20:24 | <spuk-:#xen> | moemoe: ifconfig | grep NOARP |
| 20:26 | <moemoe:#xen> | spuk-: arp is enabled on both interfaces - and afaik the NOARP only toggles answers to arp-requests. but the arp-request doesn't even arrive in the domU according to tcpdump |
| 20:27 | <spuk-:#xen> | ok |
| 20:27 | <moemoe:#xen> | it's like someone has cut the virtual cable between vif1.11 in dom0 and eth1 in domU |
| 20:28 | <moemoe:#xen> | that's the domU i have root in, but all other domUs are also not reachable |
