libvirtd for el7
by Sandro Bonazzola 24 Apr '15

24 Apr '15

Hi, I see that for EL6 gwd already has pushed a libvirtd package with version 1.2.10[1]. I got request from VDSM development to provide libvirt >= 1.2.9 for EL7 for oVirt 3.6. gwd, do you just rebuilt http://koji.fedoraproject.org/koji/buildinfo?buildID=594825 ? I'm looking at http://koji.fedoraproject.org/koji/buildinfo?buildID=628689 may this work for you? [1] http://cbs.centos.org/koji/buildinfo?buildID=251 -- Sandro Bonazzola Better technology.

Seeing dropped packets / tcp retrans on latest 4.4.1-10el6
by Nathan March 20 Apr '15

20 Apr '15

Hi All, Was troubleshooting some odd VM network issues and discovered that we're seeing dropped packets + retransmissions across multiple domU OS's and dom0 hardware platforms. xendev01 ~ # tshark -R "tcp.analysis.retransmission " -i vif7.0 Running as user "root" and group "root". This could be dangerous. Capturing on vif7.0 3.054257 xxx.xxx.xxx.196 -> xxx.xxx.xxx.145 SSH 110 [TCP Fast Retransmission] Encrypted response packet len=44 3.061949 xxx.xxx.xxx.196 -> xxx.xxx.xxx.145 SSH 1434 [TCP Fast Retransmission] Encrypted response packet len=1368 3.383880 xxx.xxx.xxx.196 -> xxx.xxx.xxx.145 SSH 1434 [TCP Fast Retransmission] Encrypted response packet len=1368 3.630911 xxx.xxx.xxx.196 -> xxx.xxx.xxx.145 SSH 1434 [TCP Fast Retransmission] Encrypted response packet len=1368 3.635964 xxx.xxx.xxx.196 -> xxx.xxx.xxx.145 SSH 1434 [TCP Fast Retransmission] Encrypted response packet len=1368 I've confirmed this is happening with linux, windows and pfsense (bsd) domU's. I've turned off every feature I can with ethtool on both the underlying bridge on the host, the vif's, and the eth's inside the domU's. I also see it on traffic inbetween vms on the same host. The domU sees packet errors on incoming traffic and outgoing looks fine, dumping on the dom0 indicates incoming packets are fine, but the reply from the domU is broken. This does not happen running the exact same VMs on some older xen 4.1.3 hosts. Reproduction is easy (for me at least), any burst of traffic will do it. I've just been running "ps auxf" over ssh to a vm to trigger. Since I'm seeing it on the host when I sniff the vif, this feels like a bug? - Nathan

CentOS 7 AMI Building
by Jason Antman 17 Apr '15

17 Apr '15

Hello, I'm new to this list, but I noticed a post from March 30th inquiring about the build scripts for the official CentOS7 AMIs. I'm also interested in this; I'm tasked with (unfortunately) spinning up some VMs in our corporate VMWare environment that are "as close as possible" to the official CentOS7 AMIs. I could attempt to reverse-engineer them and figure out all of the packages and settings, but it would be much easier if we could get access to the build scripts. I've searched as much as I know how to, and while I've found some related tooling for Docker and other services (i.e. on the CentOS GitHub account), I can't seem to find anything related to the AMIs. I know I looked into this a while ago for CentOS6, and was told that the 7 stuff would be made public. Does anyone have a pointer to it, or could someone at least post the kickstart and/or other relevant information? Thanks, Jason Antman

Hi, Regarding my gsoc proposal (xen in a box), I have developed a set of scripts to create a custom CentOS ISO which delivers Xen 4.4 stack on CentOS 6.6 with libvirt and fully bridge network settings. I have used xen scripts for networking settings.
