[libvirt] A problem about live migration of kvm
by 姚远 20 Jul '10

20 Jul '10

>From qemu-kvm-0.12.1, kvm has the function about live migration with non-shared storage. But I don't know how to use it. In the qemu monitor, "migrate -d tcp:10.1.10.42:444" which is based on shared storage is going well. I don't know how to use the command of "-b or -i" or maybe I don't know the correct format of uri. the source and destination system is Fedora-13, and the version of kvm is qemu-kvm-0.12.3. When I use the "migrate -d -b tcp:10.1.10.42:4444", the qemu monitor don't show nothing. When I use "info migrate",there shows "migrate status:failed". I don't know why? I hope someone who used this command successfully would help me, thank you.

[libvirt] [PATCH 0/8]: Revamp virsh error reporting
by Chris Lalancette 19 Jul '10

19 Jul '10

This patch series is related to a discussion Eric Blake and I had a couple of months back[1]. It essentially revamps the way that virsh does error reporting so that errors from more calls are properly reported. More details are in each individual patch.

[libvirt] iscsi support?
by Harald Dunkel 19 Jul '10

19 Jul '10

Hi folks, I would like to try out iscsi for virtual block devices. This would be very interesting especially for a migration at run time. Problem is: It still doesn't work :-(. libvirt can login to the iscsi pool, but using virsh vol-list I just get an empty list, even though /dev/disk/by-path shows the expected block devices. There was an old thread on this list describing the procedure: http://www.mail-archive.com/libvir-list@redhat.com/msg06320.html Are there any news about this? I am using libvirt 0.8.1, iet 1.4.20.1 and open-iscsi 2.0.871.3, as included in Debian Testing. Regards Harri

[libvirt] flaky network on clients/guests machines - please help!
by Horten 18 Jul '10

18 Jul '10

I've set up a redhat ( Linux 2.6.18-194.8.1.el5 #1 SMP Wed Jun 23 10:52:51 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux) box and two virtual hosts (clients/guests). The network on the host is fine, however the clients network is extremely flaky....Sometimes it connects into and out of the client, but sometimes it gives me all sorts of timeout, no route, etc messages....I've tried everything I can think of, turning on dnsmasq, nscd, and adding options single-request in resolv.conf, but nothing seems to work. The client machines are running the same os as the host....Please see below results of running strace on ssh to another machine....(I can ssh to this other machine from the host and from any other machine and at times from the clients)...Any help will be greatly appreciated.....

[libvirt] Memory
by Jaromír Červenka 17 Jul '10

17 Jul '10

Hello, Could anybody explain me a little bit what is the difference between <currentMemory> and <maxMemory>. I use qemu-kvm hypervisor*. *When I have 1024MB maxMemory and 512MB of currentMemory, I can see just 512MB in guest os (free -m).* *Is it ok? Does it have something to do with ballooning technique? What happened if guest will needs more memory than 512MB? Thank you for answers :) Kind regards, Jaromír Červenka Official openSUSE community member Web: http://www.cervajz.com/ Jabber: cervajz(a)cervajz.com MSN: jara.cervenka(a)seznam.cz Tel.: +420 607 592 687 Alt. e-mails: jaromir.cervenka(a)opensuse.org, jaromir.cervenka(a)speel.cz

This includes activities such as starting, stopping +and migrating guests between host servers, configuring and manipulating +networking, and managing storage for use by guests. + +The libvirt client libraries and utilities connect to this daemon to issue +tasks and collect information about the configuration and resources of the host +system and guests. + +By default, the libvirtd daemon listens for requests on a local Unix domain +socket. Using the B<-l>|B<--listen> command line option, the libvirtd daemon +can be instructed to additionally listen on a TCP/IP socket. The TCP/IP socket +to use is defined in the libvirtd configuration file. + +Restarting libvirtd does not impact running guests. Guests continue to operate +and will be picked up automatically if their XML configuration has been +defined.

[libvirt] [PATCH] docs: remove all generated doc files when a clean target is used
by Justin Clift 16 Jul '10

16 Jul '10

Properly removes all of the generated .html and .xml files in the docs area with make clean and make maintainer-clean. Otherwise they're just left there and get in the way when working on docs. --- docs/Makefile.am | 4 ++-- 1 files changed, 2 insertions(+), 2 deletions(-) diff --git a/docs/Makefile.am b/docs/Makefile.am index a6a6d07..463a466 100644 --- a/docs/Makefile.am +++ b/docs/Makefile.am @@ -150,10 +150,10 @@ $(python_generated_files): $(srcdir)/apibuild.py \ check-local: all clean-local: - rm -f *~ *.bak *.hierarchy *.signals *-unused.txt *.html + rm -f *~ *.bak *.hierarchy *.signals *-unused.txt *.html html/index.html \ + $(devhelphtml) $(python_generated_files) maintainer-clean-local: clean-local - rm -rf libvirt-api.xml libvirt-refs.xml rebuild: api all -- 1.7.1.1
