[libvirt] Libvirt clock/time settings doubt.
by Julio Faracco 22 Oct '14

22 Oct '14

Hi everyone! What is the method/function responsible to setup time settings in libvirt? Considering the example of libvirt documentation. <clock offset='localtime'> <timer name='rtc' tickpolicy='catchup' track='guest'> <catchup threshold='123' slew='120' limit='10000'/> </timer> <timer name='pit' tickpolicy='delay'/> </clock> ... I know where this XML will be parsed. But I don't know where libvirt will pass clock/time settings to QEMU. Can somebody explain to me or send me a documentation about it? I passed two weeks trying to discover the sequence of function calls. Thanks guys! *--* *Julio Cesar Faracco*

[libvirt] [PATCH] Add support for /run/initctl
by Rick Harris 22 Oct '14

22 Oct '14

Newer versions of Debian use `/run/initctl` instead of `/dev/initctl`. This patch updates the code to search for the FIFO from a list of well-known locations.

[libvirt] libvirt build failure on armhf (Re: [Xen-devel] [libvirt bisection] complete build-armhf-libvirt)

I don't think it is Xen specific. Our bisector has fingered the changeset below. I've had a skim of the git log from there to master and of the outstanding patches on libvir list and I don't see anything which is obviously a related fix, so I hope this is still useful/relevant. An instance of the failure can be seen at http://www.chiark.greenend.org.uk/~xensrcts/logs/30765/build-armhf-libvirt/… The logs say: util/virsocketaddr.c: In function

[libvirt] [PATCH 0/5] parallels: continue rewriting code to use sdk
by Dmitry Guryanov 22 Oct '14

22 Oct '14

This patch series replaces a series of functions, which retieve different domains info and modifies domains state with new ones, which use parallels sdk instead of executing prlctl command. These functions don't use cached domains list _parallelsConn.domains, so when we rewrite all code, we will be able to remove it.

Build with clang fails with: CC util/libvirt_util_la-virsocketaddr.lo util/virsocketaddr.c:904:17: error: cast from 'struct sockaddr *' to 'struct sockaddr_in *' increases required alignment from 1 to 4 [-Werror,-Wcast-align] inet4 = (struct sockaddr_in*) res->ai_addr; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ util/virsocketaddr.c:909:17: error: cast from 'struct sockaddr *' to 'struct sockaddr_in6 *' increases required alignment from 1 to 4 [-Werror,-Wcast-align] inet6 = (struct sockaddr_in6*) res->ai_addr; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 2 errors generated. Fix that by replacing virSocketAddrParseInternal() call with virSocketAddrParse() in the virSocketAddrIsNumericLocalhost() function. virSocketAddrParse stores an address in virSocketAddr. virSocketAddr uses a union to store an address, so it doesn't need casting. --- src/util/virsocketaddr.c | 20 ++++++-------------- 1 file changed, 6 insertions(+), 14 deletions(-) diff --git a/src/util/virsocketaddr.c b/src/util/virsocketaddr.c index 5f54e68..da0a9f1 100644 --- a/src/util/virsocketaddr.c +++ b/src/util/virsocketaddr.c @@ -890,28 +890,20 @@ virSocketAddrNumericFamily(const char *address) bool virSocketAddrIsNumericLocalhost(const char *addr) { - struct addrinfo *res; + virSocketAddr res; struct in_addr tmp = { .s_addr = htonl(INADDR_LOOPBACK) }; - struct sockaddr_in *inet4; - struct sockaddr_in6 *inet6; bool ret = false; - if (virSocketAddrParseInternal(&res, addr, AF_UNSPEC, false) < 0) + if (virSocketAddrParse(&res, addr, AF_UNSPEC) < 0) return ret; - switch (res->ai_addr->sa_family) { + switch (res.data.stor.ss_family) { case AF_INET: - inet4 = (struct sockaddr_in*) res->ai_addr; - ret = memcmp(&inet4->sin_addr.s_addr, &tmp.s_addr, - sizeof(inet4->sin_addr.s_addr)) == 0; - break; + return memcmp(&res.data.inet4.sin_addr.s_addr, &tmp.s_addr, + sizeof(res.data.inet4.sin_addr.s_addr)) == 0; case AF_INET6: - inet6 = (struct sockaddr_in6*) res->ai_addr; - ret = IN6_IS_ADDR_LOOPBACK(&(inet6->sin6_addr)); - break; + return IN6_IS_ADDR_LOOPBACK(&res.data.inet6.sin6_addr); } - freeaddrinfo(res); return ret; - } -- 2.0.2
