You can use the virtio-blk serial or file system/volume labels to distinguish them.

[libvirt] IPs via DHCP for guest domains
by Fong Vang 17 Jul '12

17 Jul '12

I'm curious to know how you are providing IPs for your Windows VMs when connected via a bridge. Since broadcasts from the VMs are going out the bridged interface, I'm thinking about implementing ebtables to block dhcp broadcasts from going in/out the interface so that dnsmasq would only respond to dhcp requests from the local guest VMs. Before I venture down this path, I thought I might ask if there's an easier way to do this with libvirt. Thanks for any help.

[libvirt] [PATCH 0/4] qemu: configurable port boundaries for remote displays
by Martin Kletzander 17 Jul '12

17 Jul '12

This series introduces a possibility to change default minimal and maximal port numbers that are used to specify a remote display port for both VNC and SPICE. Because the code was a bit messy, PATCH 1/4 cleans up few things needed to make a clean run of PATCH 2/4, that does the main change in the code. I also noticed two things that could be changed and it made sense for me to do that, but these are nowhere near any importance, so feel free to reject them if your heart feels that way. PATCH 3/4 rewords three messages and applying it would mean that they are not translated. Even though I think it makes more sense this way, I'm not a good English speaker, so that's more like an RFC. PATCH 4/4 makes more flexible port searching available, but is used on one place and because there are so many ports, it won't be that used, I guess. P.S.: this is basically v2 for https://www.redhat.com/archives/libvir-list/2012-May/msg01081.html but it changed a lot and the name is also different, so I didn't want to create any confision.

In trying to build libvirt 0.9.13 on F17, I'm hitting a link error: ... CCLD libvirt_driver_nodedev.la CCLD libvirt_driver_nwfilter.la /usr/bin/ld: cannot find -lcrypto Full log here: http://kojipkgs.fedoraproject.org//work/tasks/3678/4233678/build.log I think this comes from rbd support, from configure.ac: LIBRBD_LIBS="-lrbd -lrados -lcrypto" from this commit: http://libvirt.org/git/?p=libvirt.git;a=commit;h=74951eadef85e2d100c7dc7bd9… What's missing here? RPM BuildRequires, configure change, ...? Thanks, Cole

[libvirt] ESX: failure while performing "CastFromAnyType"
by Ata E Husain Bohra 16 Jul '12

Hi All, I am trying to extend “iscsi” support for iSCSI driver, currently am stuck at getting iSCSI target list from the hypervisor. I am using hostSystem object (propertyNameList is set to “config.storageDevice.hostBusAdapter”) to retrieve list of “HostHostBusAdapter” from ESX, but the call fails to perform “CastFromAnyType” from ObjectContent –> HostHostBusAdapter. The esx_vi_generator.input object definition looks like this: object HostHostBusAdapter String key o String device r Int bus r String status r String model r String driver o String pci o end esx_vi_generaor.py is modified as follows: "HostHostBusAdapter" : Object.FEATURE__ANY_TYPE | Object.FEATURE__LIST, Using gdb, I see the failure occurs at: esx/esx_vi.c:esxVI_List_CastFromAnyType(..) line 1631: .. if (esxVI_AnyType_Deserialize(childNode, &childAnyType) < 0 || castFromAnyTypeFunc(childAnyType, &item) < 0 || esxVI_List_Append(list, item) < 0) { goto cleanup; } .. In one of my earlier patches (subject: Add routines to interface driver) I patched esx_vi_generator.py to deserialize “string list”; as the patch is still under review I manually applied the branch to this branch but no change (did not expect change as structure does not contain any list object). I am wondering what else is missing to make it work. Any suggestion how to debug/fix this issue is highly appreciated. Thanks! Ata
