Xen on CentOS 6.4
by Luke S. Crawford 21 Jun '13

21 Jun '13

I heard talk of a centos-supported xen dom0 for CentOS 6.4, but I haven't heard talk of such a thing lately, and I haven't seen where to download it, which could just be me being stupid.

Package lists for Cloud images
by Karanbir Singh 01 Jun '13

01 Jun '13

hi Guys, As we get ready to start publishing Cloud Images ( or rather images consumable in various virt platforms, including public and private clouds ) - it would be great to have a baseline package manifest worked out. What / how many images should we build. At this time we were thinking of doing : - CentOS-5 32bit minimal - CentOS-6 32bit minimal - CentOS-5 64bit minimal - CentOS-6 64bit minimal - CentOS-5 64bit LAMP - CentOS-6 64bit LAMP What would be the minimal functional requirements people would expect from these images ? and what rpms should be installed ? Should root login be enabled or should we require people to go in via a 'centos' user. Should the image be self-updating, or should we have a post-login message that indicates outstanding updates ? -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh ICQ: 2522219 | Yahoo IM: z00dax | Gtalk: z00dax GnuPG Key : http://www.karan.org/publickey.asc

CentOS-6.4 AMI's for testing
by Karanbir Singh 28 May '13

28 May '13

hi, We are going to run a public test cycle for the CentOS AMI's that we publish as the official ones. This test will run for 1 week, ending on the 4th May, when we will do the formal release. Request: please dont use these AMI's for production, please dont use these AMI past the 4th of May. For all change and fix requests, either post to this list and we will attempt to get things turned around super quick, or find either Tru or me in #centos-devel or #centos-virt on irc.freenode.net. Our nicknames are tru_tru and z00dax respectively. These AMI's exist in us-east1 for now. Please keep them there. For release, we will have the images in the MarketPlace, as we did for 6.3. But we will also publish the AMI's in every region ( including sydney! ) and make sure the ID's are well documented, additionally, we will publish the raw backing files, so people can take these images to on-premise or non AWS resources as well. Once we have reasonalbe confidence in the images, I will convert them into EBS backed as well : ami-ede18284 CentOS-6.4/x86_64 Base OS AMI ami-43cfac2a CentOS-6.4/x86_64 Base OS + Updates/20130427 AMI ami-b5c8abdc CentOS-6.4/i386 Base OS AMI ami-d9ceadb0 CentOS-6.4/i386 Base OS + Updates/20130427 AMI Note: These AMI's have only been tested via a single instantiation, and ssh login + logout. The distro tests for these ami's are currently running, and I will report succes / fails to the list as a followup. Also, worth noting : while building the i386/updates image; about 90% of all instantiations failed with a xen/pae kernel error. I'm not sure why the aki, in this case aki-b6aa75df, seems to get confused about the disk hosted kernel type. If anyone else also sees this, let me know. for now, I'm writing this off as a flaky something. -- Karanbir Singh +44-207-0999389 | http://www.karan.org/ | twitter.com/kbsingh GnuPG Key : http://www.karan.org/publickey.asc

Re: [CentOS-virt] virt-manager like tool for Android

Look in the Play Store for 'VM Manager' - I am able to start/stop VM's with it...

This is important for things like OS installs or when do admin work where the network is down. This means I have to install a little linux machine though as none of my clients are linux shops. So I got to wondering; If I understand, virt-manager is more or less a hypervisor-aware VNC client, is it not? Is there anything equivalent for Android devices? Many of my clients have Android devices and are certainly more comfortable with those devices then with our linux appliance. I'd be interested in hearing if anyone has a similar solution to iOS devices, too. Paid apps is fine, anything that does the job is good.

Very odd mouse issue
by aurfalien 24 May '13

Hi, I'm VNCing into my KVM server and opening virt-manager. When trying to manage a newly created guest, I'm finding the mouse pointer stays on the outside of its virtual machine window. Any insight as to why its tracking so oddly? Thanks in advance, - aurf

VM Slowness
by compdoc 20 May '13

20 May '13

I hope this in the right list, but I was wondering if someone could help me with a VM I have that has lately started having problems. It had been running for years without problems. It's possible an update is causing this, but I can't say. The VM is running CentOS 5.8 and after a time, the machine begins to slow down. Things like pings or running commands lag. If I reboot the VM, it runs normally for at least a few hours, but it eventually slows again. I've tried changing the VM's virtio devices to standard devices like IDE and e1000, but it makes no difference. Currently its running virtio. Top shows that nothing is taking up significant cpu time, but even running top takes several seconds for it to open. The system is slow now, but top shows: top - 21:39:48 up 1 day, 5:27, 1 user, load average: 0.93, 1.37, 1.12 Tasks: 177 total, 1 running, 176 sleeping, 0 stopped, 0 zombie Cpu(s): 0.3%us, 0.3%sy, 0.0%ni, 98.6%id, 0.9%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2075016k total, 1484624k used, 590392k free, 64336k buffers Swap: 4128760k total, 12k used, 4128748k free, 981368k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4124 root 20 0 2444 1080 812 R 0.1 0.1 0:00.03 top 1 root 15 0 2176 692 604 S 0.0 0.0 0:02.46 init 2 root RT -5 0 0 0 S 0.0 0.0 0:00.39 migration/0 3 root 34 19 0 0 0 S 0.0 0.0 0:00.00 ksoftirqd/0 Any ideas what to look for?
