creating a domain
hi, i am a bit confused on how to start an inactive domain using the python bindings, any help would be appreciated. (inactive as in the domain was created with?virConnect.defineXML sometime in the past) looks like i have to use virDomain.create, however virDomain.create needs a defined domain xmldesc as a parameter and i am not sure on how to get that i guess if?virConnect.create was

python equiv to perl list_domains()
Hey, I'm trying to figure out a way to get a list of the running domains on a dom0. I can get the ID's but I'd prefer the names. We have another script written in perl, but I'm trying to get some other functionality in python as well as work on converting it all to python. It looks like perl has a list_domains() that will, according to the libvirt doc, "Return a list of all

VNC port confusion
Hi, I''m trying to figure out how XEN decides which VNC port a particular VM will associate with. From what little there is in the documentation, it indicates that XEN will choose 5900+DomainID. From experience, this doesn''e seem to happen. When I start a guest domain, and do "xm list" its domainID shows as "22", however, when I netstat -a , it shows listening

Re: libvirt-python Segfaults
Hi Harish, I believe the proper establishment of a connection should be done by libvirt.open() or libvirt.openAuth() or libvirt.openReadOnly(). All of them will return a functional virConnect instance. I'm not sure this segfault is worth to fix since instantiate a virConnect directly is not an expected usage. Hope this information will help you. Best Regards, Hao Liu +86-010-62608262

[PATCH v1 0/2] Implement guestfs_add_libvirt_dom.
This is only lightly tested at the moment. For context see: https://bugzilla.redhat.com/show_bug.cgi?id=1138203#c40 https://bugzilla.redhat.com/show_bug.cgi?id=1075143 https://bugzilla.redhat.com/show_bug.cgi?id=1075164 Note this is not a complete fix. At least one more libguestfs patch is required (to implement virDomainPtr in the python bindings). Plus a virt-manager patch. Rich.

virDomainBlockInfo for local volume
Hi, I am using virStorageVolGetInfo to get the volume size virStorageVol.download to download a normal file for VDSM project. I want to add support for block devices as well, I was able to see the size via virDomainBlockInfo and download via virDomain.blockPeek which is works fine for both file and block device. 1. Can I depend on virDomainBlockInfo for non block devices? 2. Does the

How to tell if a hypervisor connection has died?
Hi, What's the best way to tell if a virConnect object is not good to use anymore? (For example because the libvirtd on the other side crashed/has been stopped or because of some network failure) When I try this, the first API call I do on a broken connection yields an error with error number 38 (VIR_ERR_SYSTEM_ERROR) and all subsequent calls yield an error number 1

[PATCH libguestfs v3] lib: Handle slow USB devices more gracefully.
Libvirt has a fixed 15 second timeout for qemu to exit. If qemu is writing to a slow USB key, it can hang (in D state) for much longer than this - many minutes usually. The solution is to check specifically for the libvirt EBUSY error when this happens, and retry the virDomainDestroyFlags operation (indefinitely). See also the description here:
