[libvirt] [PATCH] qemudDomainCreate check if domain is already active
by Guido Günther 01 Aug '08

01 Aug '08

Hi, currently virsh create foo.xml overwrites running domains. In case of qemu this leaves detached qemu processes around and the domain creation fails later on being unable to start other domains afterwards - not nice. Attached patch checks if we already have a running domain by that name and in this case refuses to create a new domain from xml by that name. Probably this check needs to be pushed further upward since this might affect other hypervisors too, haven't checked that though. Cheers, -- Guido

[libvirt] listing domains on Fedora 8 XEN kernel
by Steve Oliphant 01 Aug '08

01 Aug '08

I am having a problem being able to get domain information in an Fedora 8 XEN environment.The code does not receive an error status on the XEN kernel and does not get any information. The same code running on the non XEN kernel works fine. I am running default configuration files. Is this a known issue? Do I need to tweak the configuration files? Is there anything else I need to do get the code to work on the XEN kernel? Please point me in the right direction. If any other information is required to assist in answering my question, please let me know. Thank you in advance for your help.

[libvirt] what ever happened to the SCSI HBA storage backend?
by David Lively 31 Jul '08

31 Jul '08

Hi Folks - I see Daniel Berrange submitted a SCSI HBA storage backend in March. What ever happened to that? I'd be happy to pick this up if there's more work to do (is there a code base later than the posted patch?) In the longer run, I'm looking towards adding support necessary for FC environments (like multipath). Also, it seems (to my iSCSI-ignorant mind) that iSCSI should be just another flavor of the SCSI driver (kind of like netfs is a flavor of the fs driver ...). Is anyone working on such a refactoring? Thanks, Dave

[libvirt] [PATCH 0/2] Detailed XML errors (with thread-local storage this time)
by Richard W.M. Jones 30 Jul '08

I've just seen Daniel Veillard's message about the '_private' field. In the meantime here is a solution using thread-local storage implemented on top of pthreads, which may be of interest.
