[libvirt] vhost-net on ethernet interface type
by Raja Sivaramakrishnan 22 Dec '12

22 Dec '12

Hello, I would like to enable vhost-net on an interface of ethernet type. However, this doesn't work, probably due to the following code in libvirt. if (actualType == VIR_DOMAIN_NET_TYPE_NETWORK || actualType == VIR_DOMAIN_NET_TYPE_BRIDGE || actualType == VIR_DOMAIN_NET_TYPE_DIRECT) { /* Attempt to use vhost-net mode for these types of network device */ Can VIR_DOMAIN_NET_TYPE_ETHERNET also be included in the check above? Or is there some reason to disable vhost-net for this type? Thanks, Raja

[libvirt] [PATCH 0/8] Dump domain's IP addresses
by Michal Privoznik 22 Dec '12

22 Dec '12

It's been a while since I tried get this in. I've reworked the patches, the exposed API, and start new round of reviews. Moreover, during work I've come to point, where extending qemu guest agent seemed wise: http://lists.nongnu.org/archive/html/qemu-devel/2012-12/msg03264.html Therefore I am introducing 'flags' field, which can contain some boolean values we don't have yet, e.g. IFF_UP, IFF_PROMISC, etc. Re: 'dstaddr' field in struct _virDomainInterfaceIPAddress; It's basically a join of: union { char *dstaddr; /* for IFF_POINTOPOINT interface */ char *broadaddr; /* for IFF_BROADCAST interface */ } Since an interface cannot has both flags set (see man 3 getifaddrs) I've joined both into one 'char *dstaddr'. I know it is not mnemonic as the union, so I left it for discussion. I can change it if you want to.

[libvirt] [PATCH v2 0/28] Rename files in src/util to have a 'vir' prefix
by Daniel P. Berrange 21 Dec '12

21 Dec '12

Currently the files in src/util are 50/50 split between those having a 'vir' prefix and those which don't. Finish the job by remaining all remaining files to have a 'vir' prefix too, guaranteeing that they can't clash with system headers[1]. The only case which was not a plain rename, was merging processinfo.{c,h} into the virprocess.{c,h} since the functionality logically belongs together. At the end src/Makefile.am is updated to sort util files alphabetically. Left as further work - make sure all functions in these files also have a 'vir' prefix. eg dnsmasq, ebtables, iptables, usb and pci files are violators in this regard. Also left, much of virutil.c should move into virfile.c Changes in v2: - Rebased to latest GIT - Turned on rename detection to make review easier Daniel [1] Not a theoretical problem - we already hit a clsah on 'usb.h' before forcing us to use 'hostusb.h' and 'memory.h' clashes with a system header but we never noticed so far.
