[libvirt-users] Restarting iptables and libvirtd
by Brian Pitts 10 Sep '10

10 Sep '10

Hi, If I issue the commands # service libvirtd stop # service iptables stop # service iptables start # service libvirtd start the iptables rules that enable NAT on my virtual networks are not created when libvirtd is started, even though the networks are set to autostart and 'virsh net-list' shows them as active. The rules are only created if I run net-destroy and net-start. Is this the expected behavior? I would have thought that restarting libvirtd would ensure the necessary iptables rules are in place for networks marked as autostart. I would also have though that net-list would not show networks as active if the iptables rules needed for them to work were not in place. -- Brian Pitts Systems Administrator | EuPathDB Bioinformatics Resource Center 706-542-1447 | bdp(a)uga.edu | http://eupathdb.org

[libvirt-users] Status of libvirtd on BSD/OSX?
by Mitchell Hashimoto 09 Sep '10

09 Sep '10

Hello, I've done some research prior to this and the answer is clear that libvirtd doesn't compile on BSD or OSX, but I'd like to know more details about this, if I can have a bit of your time: * Are there any current efforts to get libvirtd running on BSD? * What are the blockers to getting it running? * My main goal is really to, at first only control VirtualBox, so KVM/Xen/etc is not an issue. I realize that KVM and some other hypervisors obviously can't be supported on BSD, but if I could just start by compiling libvirtd for VirtualBox on BSD that would be a big win in and of itself. Thanks, Mitchell

[libvirt-users] kqemu
by Zvi Dubitzky 08 Sep '10

08 Sep '10

Hi we have a Debian 64 bit system with qemu 0.9.1-10 ( uname -a = 2.6.26-2-amd64) installed . kvm is included and loaded to memory . Still when we create a VM we sometimes get the following error message: libvir: QEMU error : internal error unable to start guest: You do not have enough space in '/dev/shm' for the 499 MB of QEMU virtual RAM. To have more space available provided you have enough RAM and swap, do as root: mount -o remount,size=515m /dev/shm Or disable the accelerator module with -no-kqemu after we do the mount we can create the VM . Does that mean that kvm is not active because it seems that kqemu is an old way to do the duties of kvm e.g supply memory to VMs via /dev/shm thanks Zvi Dubitzky Email:dubi@il.ibm.com IBM Haifa Research Laboratory Phone: +972-4-8296182 Haifa, 31905, ISRAEL

[libvirt-users] override DNS server address?
by steven765＠yahoo.com 07 Sep '10

Is there a spot in the xml i'm not seeing to identify the network DNS server. Currently it's defaulting to a.b.c.1 I'm running my own though on a different address and can't find where to configure it in the xml schema or could I override it in DNSMASQ? Thanks Steve

by Joel Miller 06 Sep '10

06 Sep '10

Hi List, I've checked RHEL6 beta2, it's libvirt 0.8.1, but I need 0.8.3 to support vSphere 4.1, I know I can compile it by myself, but our Red Hat's customer wanna have "half official" rpm package for their test, anyone would help me to make rpm for RHEL5.5? And, do we have any roadmap about libvirt 0.8.3 to be official rpm package in RHEL6?

[libvirt-users] C, C++ or Python programming tutorial/manual/guide for libvirt
by Lucas Arbiza 01 Sep '10

01 Sep '10

Hi, I want to develop an application to manage KVM virtual machines. I've been looking for something that helps me to start programming using libvirt in C/C++. The only one documentation I found is in this link: http://libvirt.org/html/libvirt-libvirt.html. Neither Google has helped me! That does not look like a good way to start. So, do you know some useful C, C++ or Python tutorial for libvirt? I prefer C or C++. Thanks in advance. __ Lucas Arbiza email: lucas.arbiza(a)gmail.com celular: +55 (55) 9152 7561 skype: lucas.arbiza <http://br.linkedin.com/in/lucasarbiza> <http://www.google.com/profiles/lucas.arbiza>

[libvirt-users] Decent How-To now on the wiki for setting up Transport Layer Security
by Justin Clift 30 Aug '10

30 Aug '10

Hi all, For anyone that's interested in setting up TLS with libvirt, but hasn't gotten around to it yet, there's a decent guide on the wiki now: http://wiki.libvirt.org/page/TLSSetup It's user focused (ie SysAdmin's), and has lots of pics explaining concepts, plus shows what needs to be done, and shows how to do it. Please note, it doesn't cover SASL, it's just plain host based TLS. Very much open to feedback on it, if people have suggestions for improvement. Hope that helps. :) Regards and best wishes, Justin Clift
