[libvirt] [PATCHv3 0/4] Automaticaly fill <memory> element for NUMA enabled guests

[libvirt] [PATCH] parallels: Cleanup partly opened drivers on connect open failure
by Michal Privoznik 05 Mar '15

05 Mar '15

Well, the parallelsConnectOpen() joins several sub-driver openings into one big if condition. If any of sub-driver fails to open, the whole API finishes immediately. The problem is, sub-drivers may have left some memory allocated. Fortunately, we have a free function for that: parallelsConnectClose(). This is, however, not prepared for partially allocated driver structure. So, prepare the free function for it and call it at the right place, in the if body.

[libvirt] [libvirt-designer][PATCH] Makefile: Build tests at the same time as the rest
by Michal Privoznik 04 Mar '15

04 Mar '15

Currently, since we were using check_PROGRAMS in the Makefile template, the test program build was postponed until 'make check' was run. That's not optimal. Lets build (not run!) test program in the 'make all' phase.

[libvirt] [PATCH] storage: tweak condition to properly test lseek
by Erik Skultety 04 Mar '15

04 Mar '15

According to the POSIX standard, off_t (returned by lseek) is defined as signed integral type no shorter than int. Because our offset variable is defined as unsigned long long, the original check was passed successfully if UINT64_MAX had been used as offset value, due to implicit conversion.

by Erik Skultety 04 Mar '15

[libvirt] overlayfs support to lxc driver
by Vasiliy Tolstov 04 Mar '15

04 Mar '15

Hello. I'm interesting in implementing overlayfs support to lxc libvirt driver. As i see i simply can utilize filesystem type='template' for this usage. In case os template fs i need to mount with lowerdir /var/lib/libvirt/filesystems/template to /var/lib/libvirt/filesystems/name But i have problem: overlayfs fs need upperdir that store differences and mountpoint that used by clients. In case of libvirt usage - upperdir need to be places in /var/lib/libvirt/filesystems, but where i can put mountpoint dir ? /var/run/libvirt or in /tmp/libvirt-XXXXX ? Also what is the preferred way to integrate overlayfs support to libvirt? I can addd mount type to filesystem type='mount' or use (like now) template type. What is the preferred way? Thanks -- Vasiliy Tolstov, e-mail: v.tolstov(a)selfip.ru jabber: vase(a)selfip.ru
