| 03:59 | <forrest_2006> | what's the semantics of pause/unpause? |
| 03:59 | <forrest_2006> | before pause a domain, the date in guest OS is "Wed Jan 23 21:04:43 EST 2008" |

| 04:00 | <forrest_2006> | 2 minutes later, it's unpaused, then the date should be "Wed Jan 23 21:04:43 EST 2008" or "Wed Jan 23 21:06:43 EST 2008"? |

| 04:05 | <forrest_2006> | In RHEL5.1 I found that a FV domain is "Wed Jan 23 21:04:43 EST 2008" , a PV domain is "Wed Jan 23 21:06:43 EST 2008". which is the correct semantics of pause of unpause? |

| 11:02 | <PPmarcel> | good evening |
| 11:03 | <PPmarcel> | i have a weird problem |
| 11:04 | <PPmarcel> | when i try to connect to my xenserver with xencenter, i have a message 'connection failed' when i attempt to connect |
| 11:04 | <PPmarcel> | i use right passwords, my xenserver and xencenter pc are in the same vlan |
| 11:04 | <PPmarcel> | they can ping each other, and i can open a ssh link from my xencenter computer to my xenserver |
| 11:05 | <PPmarcel> | but from xencenter, i can't :/ |
| 11:06 | <PPmarcel> | So i ask me if xenbr1 interface is the one where i can connecting to the server, from xencenter ? |
| 11:14 | <danp1> | the people in this channel only work on the open source Xen |
| 11:14 | <danp1> | if you want help with Citrix's closed source apps you need to use their forums / support channels |
| 11:16 | <icarus901> | danp1, how up to date are you with qemu-vnc-xenstore interaction |

| 11:18 | <icarus901> | i'm having some grief with the previously reliable vnc-port item |
| 11:19 | <danp1> | icarus901: what about it ? |
| 11:22 | <icarus901> | danp1, previously qemu-dm would xenstore-write-vnc-port (3.0.4-1 and iirc 3.1) to store the relevant port for a given domain |
| 11:22 | <icarus901> | but i suspect something about the semantics changed |
| 11:22 | <icarus901> | it no longer gets written |
| 11:23 | <icarus901> | if this doesnt sound familiar, i'll do some more digging to pinpoint the issue or cook up a patch |

| 11:36 | <icarus901> | danp1, thank you - that's good to know..i suppose i'll pull from mercurial again |

| 14:40 | <icarus901> | is it true that modifications in recent builds place vnc information in a domain's vfb data as 'location' rather than (device (console (vnc-port blah) ) ) |
| 14:40 | <icarus901> | danp1, that's to you if you know offhand and also to any others who are familiar with this particular portion of the code |

| 19:32 | <tom> | I'm having issues with performance on a 8cpu box |
| 19:32 | <tom> | xentop shows almost no cpu use, and processes in the dom are getting stuck in D state, but there's not much disk IO either |
| 19:33 | <tom> | xen 3.0.3-1 on 2.6.20 kernel, packages from debian backports |
| 19:34 | <tom> | I'm using the credit scheduler, and all doms are set to 0 cap and 256 weight |
| 19:35 | <brendan> | what's the disk backend? |
| 19:37 | <tom> | lvm |
| 19:37 | <brendan> | any other disk load on the device in dom0? |
| 19:37 | <tom> | no |
| 19:37 | <tom> | its 8 disk sata on 9650SE |
| 19:38 | <brendan> | might try pinning dom0 to one CPU, but I don't have any good ideas |
| 19:40 | <brendan> | also experiment with pausing other domains that might be competing |
| 19:41 | <tom> | interesting, i just ran time /bin/bash -c 'dd if=/dev/zero bs=1024k count=1024 | md5sum' |
| 19:42 | <movement> | hey brendan - I've removed the fast-suspend entry in xenstore, but still occassionally get a linux domU switching a device from state 0 straight to state 4 (XenbusConnected) sometimes |
| 19:42 | <movement> | that shouldn't happen, right? |
| 19:42 | <tom> | and it completed in 5.6 seconds, and sent a cpu to 100%, so it seems to be disk related |
| 19:46 | <brendan> | movement: I don't really know, to be honest. I thought some of that logic was buried in the particular devices |
