[libvirt] ESX [03/12]: Add esxDomainXMLToNative()
by Matthias Bolte 14 Sep '09

14 Sep '09

Extend and cleanup the VMX to domain XML mapping. Add the domain XML to VMX mapping functions. * src/esx/esx_driver.c: add esxDomainXMLToNative() * src/esx/esx_vmx.[ch]: add esxVMX_SCSIDiskNameToControllerAndID(), esxVMX_IDEDiskNameToControllerAndID(), esxVMX_FloppyDiskNameToController(), esxVMX_GatherSCSIControllers(), add basic handling for the VMX guestOS entry to distinguish between i686 and x86_64, make SCSI virtualDev VMX entry optional as it should be, map the VMX networkName entry to the domain XML interface bridge name, add basic mapping for serial devices in pipe mode, add several esxVMX_Format*() functions

[libvirt] Interface driver and ESX support
by Shahar Klein 13 Sep '09

13 Sep '09

I'm trying to get a feel of the python binding and the esx driver Trying to get the number of interfaces hit(as anticipated) a non-support wall: Traceback (most recent call last): File "test.py", line 362, in ? vmm.refresh() File "test.py", line 189, in refresh print self.conn.numOfDefinedInterfaces() File "/usr/lib/python2.4/site-packages/libvirt.py", line 1347, in numOfDefinedInterfaces if ret == -1: raise libvirtError ('virConnectNumOfDefinedInterfaces() failed', conn=self) libvirt.libvirtError: this function is not supported by the hypervisor: virConnectNumOfDefinedInterfaces I'm wondering how to fix it can I register the esx driver as the interface driver? so I can use the ESX web-services to handle all the interface issues that normally(?) netcf would handle? if yes - how is it done? I thought that configure --without-netcf would do the trick(it didn't-I think) Thanks Shahar

Ok, but that's only an argument to have extboot as a workaround for bioses not yet supporting scsi and virtio natively, isn't it? I'm thinking long-term here, not arguing against a extboot-based short-term solution. Jan -- Siemens AG, Corporate Technology, CT SE 2 Corporate Competence Center Embedded Linux

[libvirt] vnet<X>'s & interfaceStats().. KVM device numbering confusion?
by r-c＠rocketmail.com 12 Sep '09

12 Sep '09

Hi libirt-list, I am attempting to migrate from Xen->KVM and am having a little trouble understanding the new vnet<X> interface numbering scheme and how to use it to collect statistics of the interface using the interfaceStats() function. In Xen, the ID for a given domain was know, and a corresponding vif<ID>.0 interface was brought up so it was easy to grab the stats (amongst other things). Under my new KVM config I've realised that vnet<X> is brought up in a 'first free' fashion as opposed to a counter in the Xen case. This leaves me scratching my head a little bit, say I have a domain which has ended up with ID = 8, but may for instance have network 'vnet1' associated with it. I'm not sure how I can determine any association between the domain & which interface belongs to it! (e.g. a call to domain.interfaceStats() requires the correct network interface as a parameter). Surely I must be missing something here? Anyone have any advice/workaround for this situation? Ideally I would like to either be able to hardcode vnet-labels in the XML description (tried but it's ignored), or otherwise keep vnet numbering in sync with domain ID. Thanks in advance, Ravi

[libvirt] Postponing 0.7.1 release by a couple of days
by Daniel Veillard 11 Sep '09

11 Sep '09

We still commited quite a bit in the last few days and I think taking a couple of extra days for testing is a bit safer, so I suggest to make the release only on Tuesday. So we have today and this week end for testing, push fixes if needed on Monday and I would make the release early on tuesday, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt][qemu] unable to start guest under kvm
by Anton Protopopov 11 Sep '09

11 Sep '09

Hi, all. I have the following problem: when I creating a guest, libvirt resolves <type ... machine="pc" ...> to <type ... machine="pc-0.11" ...> as provided by http://www.mail-archive.com/libvir-list@redhat.com/msg15014.html When <type ... machine="pc-0.11" ...> or <type ... machine="pc-0.10" ...> is set, I get two following errors (which would happend is unpredictable) # virsh -c qemu:///system start $d error: Failed to start domain Desktop error: internal error unable to start guest: Supported machines are: pc Standard PC (default) isapc ISA-only PC and # virsh -c qemu:///system start $d error: Failed to start domain Desktop error: monitor socket did not show up.: Connection refused When <type ... machine="pc" ...> is set, this guest starts successfully. The domain type of this machine is "kvm". But I have # qemu --version && kvm --help | head -1 QEMU PC emulator version 0.11.50, Copyright (c) 2003-2008 Fabrice Bellard QEMU PC emulator version 0.10.0 (kvm-devel), Copyright (c) 2003-2008 Fabrice Bellard on that HN. - why does libvirt sets machine to "pc-0.11" even if kvm qemu version is 0.10? - why does an error occure if I set <type ... machine="pc-0.10 ... ">
