Hi, I'm trying to figure out what controls the number if in-flight virtio block operations when running linux in qemu on top of a linux host. The problem is that we're trying to run as many VMs as possible, using ceph/rbd for the rootfs. We've tripped over the fact the the memory consumption of qemu can spike noticeably when doing I/O (something as simple as "dd" from

Hi, I'm running into some problems with libvirt and hoping someone can point me at some instructions or maybe even help me out. First, are there any requirements on qemu version in order to use the "numatune" and/or "cpu/numa/cell" elements? Or do they use cgroups and not the native qemu numa support? Second, are there any instructions on how to set up cgroups? I

I can''t seem to find a sane way of running storeconfigs on the new AWS server environment I''m working on. - SQLite is not an option. It becomes unusable far too quickly. - Using a mysql adapter doesn''t seem to work properly. - I quickly run into bug #9290<http://projects.puppetlabs.com/issues/9290>again and again. Which after 2 years STILL

I have a test method (below). def test_save_failed post( :edit, :record => StatusChanger.invalid_data_hash) assert_response :success assert_template ''edit'' assert assigns(:record) assert_equal false, assigns(:record).valid? end This particular method is part of a larger set of functional tests. If I run, $ ruby controller_test.rb -n

When running "virsh capabilities" one of my systems shows a couple entries for "pages" under host/cpu. (One for 4KB, one for 2MB.) On my other system I'm missing the "pages" entries. Is there something that I need to configure, or is this a libvirt version issue, or what? The system with the "pages" entries is running 1.2.9, while the system

Hi, I hope someone can help me out. I'm running into an issue with libvirt 1.2.12 reporting "operation failed: domain is no longer running" for a migration when qemu thinks it was fine. The steps are: 1) create guest with stress test running in it to dirty memory at a high rate (fast enough that it would not normally complete live-migration) 2) trigger live migration with

Is anyone here running Smoothwall Appliance as a VM in Xen? We''re running it right now, but it''s running fully virtualized instead of para-virtualized. Anyone know if it can run as a PV? It crashed yesterday with only a 100 user sessions on it. Not much in the log except: [2010-12-06 15:03:31 7341] WARNING (image:559) domain prxy3: device model failure: pid 22922: malfunctioning

Hi, We've run into a problem with libvirt 1.1.2 and are looking for some comments on whether this is a bug or design intent. We're trying to use migrateToURI() but we're using a few things (numatune, vcpu mask, etc.) that may need adjustment during the migration. We found that migrateToURI2() mostly works if we use XML created by copying the domain XML from the running instance

Hi, I've got a high bandwidth link with fairly high latency. I stumbled over the "High Performance SSH" patch at "http://www.psc.edu/networking/projects/hpn-ssh/", also discussed at "http://www.cyberciti.biz/tips/sshd-server-optimization.html". Why hasn't support for this sort of thing gone into the mainline OpenSSH? Thanks, Chris
