[libvirt] [PATCH] pass stub driver name instead of pciFindStubDriver
by Chunyan Liu 11 Jan '13

11 Jan '13

Pass stub driver name directly to pciDettachDevice and pciReAttachDevice to fit for different libvirt drivers. For example, qemu driver prefers pci-stub, but Xen prefers pciback.

[libvirt] Attaching an "Internal Address"
by Varun Bhatnagar 11 Jan '13

11 Jan '13

Hi, I am trying to attach an internal address to my domain. So for that I am defining the following syntax in my xml file: but it is giving the following error: Tried giving interface type as network but that is adding Host-only type interface. Can anyone please suggest what can be the possible solution. I think it is some problem with the source network. Do I have to define any internal network before in any interface? If yes then how? Any help will be appreciated. Thanks in advance.

Hi, Once again, I'll be lazy and just copy&paste an IRC conversation but please don't hesitate to ask if something needs clarification: <zeenix> am i missing something or there is no way to 'upgrade' a read-only connection to a normal one? <eblake_out> zeenix: looks like you have to create a new connection if you want new privileges <eblake_out> although you may want to float it by the list to see if a new API for upgrading an existing connection makes sense <eblake_out> especially in light of danpb's work-in-progress on adding fine-grained ACLs <zeenix> ah ok <zeenix> eblake_out: we'd like to connect to system libvirt as well by default in boxes <zeenix> but would be nice to avoid the polkit dialog until we really need full-access -- Regards, Zeeshan Ali (Khattak) FSF member#5124
