[libvirt] [PATCH 0/2][RESEND] Fix problems on using lxc with cgroup ns subsystem
by Ryota Ozaki 23 Jun '10

23 Jun '10

The patch set fixes two problems of lxc that happen when ns subsystem is enabled with memory subsystem at the same time. The fist problem is that cgroup subdirectories that are automatically created by ns subsystem remain after domain shutdown. The second problem is that memory usage is not properly accounted.

[libvirt] [PATCH] Improve some error messages about unsupported APIs/URIs
by Daniel P. Berrange 23 Jun '10

23 Jun '10

If there is no driver for a URI we report "no hypervisor driver available" This is bad because not all virt drivers are hypervisors (ie container based virt). If there is no driver support for an API we report "this function is not supported by the hypervisor" This is bad for the same reason, and additionally because it is also used for the network, interface & storage drivers. * src/util/virterror.c: Improve error messages --- src/util/virterror.c | 8 ++++---- 1 files changed, 4 insertions(+), 4 deletions(-) diff --git a/src/util/virterror.c b/src/util/virterror.c index 96dd1e7..9f632ec 100644 --- a/src/util/virterror.c +++ b/src/util/virterror.c @@ -760,15 +760,15 @@ virErrorMsg(virErrorNumber error, const char *info) break; case VIR_ERR_NO_SUPPORT: if (info == NULL) - errmsg = _("this function is not supported by the hypervisor"); + errmsg = _("this function is not supported by the connection driver"); else - errmsg = _("this function is not supported by the hypervisor: %s"); + errmsg = _("this function is not supported by the connection driver: %s"); break; case VIR_ERR_NO_CONNECT: if (info == NULL) - errmsg = _("no hypervisor driver available"); + errmsg = _("no connection driver available"); else - errmsg = _("no hypervisor driver available for %s"); + errmsg = _("no connection driver available for %s"); break; case VIR_ERR_INVALID_CONN: if (info == NULL) -- 1.6.6.1

[libvirt] Comments on the libvirt java changes
by Bryan Kearney 23 Jun '10

23 Jun '10

Luis: I have looked over the patches which you have posted up at http://github.com/LuisCM/libvirt-java-0.4.6/commits/master. First and formost, thank you for your interest in libvirt and hte java bindings. A couple of minor comments. It would be easier for me if the repo did not have a version number, and if it were just a clone of the main repo with changes on top of it. Second, please try and remove trailing white spaces from flies you check in. Most IDE's allow this by default. Finally, please try and seperate out style/formatting chnages from functional ones. It makes it easier to know what to bring in. Now.. Commit fc394b15e6e1f0f5135bdfd3335b6cc26b635ae7 =============================================== This was a big change, but the pattern I see is: 1) Make everything final 2) ( xxxx ) instead of (xxx) 3) Comment clean up. 4) Explict use of this. Is that correct? Are there other items in there? If so, on (1) what is the reason for maknig everything final? Is this a performance choice? I personally tend to make nothing private since it limits what others can do with the code. Final seems to add in similar contraints. Commit 44055c0ab13c56190e9cc00f71b71e23b2fc7c9b =============================================== This looks like adding some better toStrings. Is that correct? -- bk

[libvirt] how to setup libvirt development environment...
by Avdhoot Joshi 22 Jun '10

Hi, Installed RHEL 5.5 on AMD Opteron. [root@wlng-ppcore-nd3 ~]# uname -a Linux wlng-ppcore-nd3 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux [root@wlng-ppcore-nd3 ~]# virsh version Compiled against library: libvir 0.6.3 Using library: libvir 0.6.3 Using API: QEMU 0.6.3 Running hypervisor: QEMU 0.9.1 This is the default version of virsh using libvirt 0.6.3. Downloaded libvirt 0.8.1, configured it as follows: $ configure $ make $ make install What should be done so that virsh uses the latest 0.8.1 libvirtd binary, how to completely stop 0.6.3? I want to execute a program using virDomainMemoryStats which is not available in 0.6.3 libvirt. Thanks, Avdhoot

[libvirt] [PATCH] Don't leak open fd to virsh in libvirt-guests init script
by Jiri Denemark 22 Jun '10

Running virsh while having /var/lib/libvirt/libvirt-guests file open makes SELinux emit messages about preventing virsh from reading that file.

[libvirt] [PATCH v3] nwfilter: fix loadable module support
by Stefan Berger 22 Jun '10

22 Jun '10

Following Daniel Berrange's multiple helpful suggestions for improving this patch and introducing another driver interface, I now wrote the below patch where the nwfilter driver registers the functions to instantiate and teardown the nwfilters with a function in conf/domain_nwfilter.c called virDomainConfNWFilterRegister. Previous helper functions that were called from qemu_driver.c and qemu_conf.c were move into conf/domain_nwfilter.h with slight renaming done for consistency. Those functions now call the function expored by domain_nwfilter.c, which in turn call the functions of the new driver interface, if available.
