[libvirt] virsh version problem with remote connection
by Matthias Bolte 01 Jun '11

01 Jun '11

virsh version does basically this hvType = virConnectGetType(...) virGetVersion(..., hvType, ...) [...] Assuming a remote connection virConnectGetType calls the remote driver that returns the type of the underlying driver on the server side, for example QEMU. Then virGetVersion compares hvType to a set of strings that depend on configure options and returns LIBVIR_VERSION_NUMBER in most cases. Now this fails in case libvirt on the client side is just compiled with the remote driver enabled and the server side has the actual driver such as the QEMU driver. It just happens to work when the actual driver is compiled in on client and server side. But that's not the case here. freebsd# ./tools/virsh -c qemu+tcp://192.168.178.22/system version Compiled against library: libvir 0.9.2 error: failed to get the library version error: this function is not supported by the connection driver: virGetVersion This is not FreeBSD specific, happens on Windows as well due to the similar drivers configuration. The problem is that virConnectGetType returns QEMU, but virGetVersion on the client side only accepts Remote as hvType due to all other drivers being disabled on the client side. I'm not sure how to fix this properly, does anyone have some idea? Matthias

[libvirt] [PATCH] build: consistently use CFLAGS
by Eric Blake 31 May '11

31 May '11

According to the automake manual, CPPFLAGS (aka INCLUDES, as spelled in automake 1.9.6) should only include -I, -D, and -U directives; more generic directives like -Wall belong in CFLAGS since they affect more phases of the build process. Therefore, we should be sticking CFLAGS additions into a CFLAGS container, not a CPPFLAGS container. * src/Makefile.am (INCLUDES): Move CFLAGS items...

Probably more for the user list than this one. However... I've used 'avahi' successfully to get resolution in the clients. It implements the 'Bonjour' no configuration system. Obviously the client image has to have the avahi daemons installed and correctly configured. Once you have that working in the client and the correct settings in your resolver on the host, then you can ssh into 'xyz.local' and it resolves nicely. Rgs Neil

[libvirt] [PATCH] openvz: Handle getline failures in openvzReadConfigParam properly
by Matthias Bolte 31 May '11

31 May '11

The regression fix in 3aab7f2d6b068f0 altered the error handling. getline returns -1 on failure to read a line (including EOF). The original openvzReadConfigParam function using openvz_readline only treated EOF as not-found. The current getline version treats all getline failures as not-found. This patch fixes this and distinguished EOF from other getline failures. --- src/openvz/openvz_conf.c | 7 ++++++- 1 files changed, 6 insertions(+), 1 deletions(-) diff --git a/src/openvz/openvz_conf.c b/src/openvz/openvz_conf.c index 2cccd81..bf6ee2c 100644 --- a/src/openvz/openvz_conf.c +++ b/src/openvz/openvz_conf.c @@ -659,7 +659,12 @@ openvzReadConfigParam(const char *conf_file, const char *param, char **value) return -1; VIR_FREE(*value); - while (getline(&line, &line_size, fp) >= 0) { + while (1) { + if (getline(&line, &line_size, fp) < 0) { + err = !feof(fp); + break; + } + if (!
