Re: [libvirt-users] ESX support

Hi Matthias, Sorry for the late reply. I was on travel with limited network access last week. That sounds great, if you need any help or someone to test stuff, please let me know since I am highly interested in helping in any way I can. First question, when I am testing can I use VMWare Workstation on my laptop as a replacement for a full fledged for just testing API and libVirt access? If so I can set that up on my F12 box and start running some tests with libvirt and cobbler. Any new updates on the storage and network efforts? What are the basic requirements that you are going to try to initially hit. I assume there is alway more you could do but what's your 1.0 'good to go' set?

[libvirt-users] libvirt: C++ or Java
by Gokhale, Shashibhushan 09 Apr '10

09 Apr '10

Hello, I am planning to develop a management application for managing Redhat Xen and Redhat KVM hypervisors. I am evaluating the Java bindings versus the C++ version of libvirt. As part of evaluation, I could not find meaningful answers to the questions below. Hence, I thought that people on this mailing list would be the most appropriate to comment on them. Can you please let me know your views? 1. Are all functions that are available in C API available in Java? 2. Are Java bindings added along with every enhancement to C API? 3. If answer to above question is negative, typically how long does it takes for the addition of Java bindings for the enhancement? 4. Most of libvirt based third party management applications use which of Java bindings or C API? 5. What are your good/bad experiences while using either of C API or Java bindings? 6. What is your concluding personal recommendation? And finally, since libvirt is a Redhat Emerging Technology project, does Redhat or any other third party service providers provide paid assistance, support? Thanks, Shashi

[libvirt-users] libvirt on Debian - can I safely upgrade?
by Thomas Lutz 04 Apr '10

04 Apr '10

Hi there, I'm currently using libvirt 0.4.6 from the Debian sources with 6 VMs running and since I'm getting random crashes of one of the VMs without any logfile entry in either host or guest (libvirt debugging not turned on as I found out about it just today) I want to upgrade to the latest version (0.7.7 - I guess) from Debian backports. Is this huge upgrade safely possible with just switching sources to backports? Or can I expect problems? Rebooting the VMs is obligatory at the end of the upgrade? Thanks in advance and best regards, Thomas Lutz

[libvirt-users] Creating a private network
by Brown, Matt D. 02 Apr '10

02 Apr '10

I am trying to create a separate private network between the host (domain 0) and the guests. Using virsh, I created a bridge network, virbr1. I can successfully add guest interfaces to the bridge network and communicate between the guests. However, I am unable to communicate between the host and any of the guests. I created eth0:1 on the host and configured virbr1 to forward to eth0:1 (mode="route" dev="eth0:1"), but there is still no communication. I don't think creating eth0:1 is the right thing to do. I think I need to create a virtual interface on domain 0 that is part of the bridge network, virbr1. However, when I run virsh attach-interface with domain-0, it fails. What am I missing?? Matt OS: RHEL 5, Xen kernel virbr1 Bridge Network (First attempt) <network> <name>private</name> <bridge name="virbr2" /> <ip address="169.254.1.1" netmask="255.255.0.0"> </ip> </network> virbr1 Bridge Network (First attempt) <network> <name>private</name> <bridge name="virbr2" /> <ip address="169.254.1.1" netmask="255.255.0.0" /> <forward mode="route" dev="eth0:1" /> </network>

What initiators does libvirt support for the iSCSI pool?
