[libvirt] Job Control, Google Summer of Code
by Tucker DiNapoli 20 May '14

20 May '14

Hello everyone, My name is Tucker DiNapoli and I'm going to be working on libvirt this summer for the google summer of code. My project is to implement job control in the storage driver. In order to do that I am first going to create a unified api for job control in libvirt (as it is currently implemented seperately in both the qemu and libxl drivers). I'm currently working on the api for job control and I have some ideas that I'll post on the mailing list soon. If anyone has any ideas or requests re job control I'd be happy to hear them. I'm on the #virt irc channel as tuckerD, I look forward to working on libvrt this summer. Tucker Dinapoli

[libvirt] [bug] problem with python interface, dom.vcpus() cpu info doesn't match cpu map
by Chris Friesen 20 May '14

20 May '14

Hi, I was playing around with vcpupin and emulatorpin and managed to get into a strange state. From within python I get the following: (Pdb) dom = self._lookup_by_name(instance.name) (Pdb) dom.vcpus() ([(0, 1, 5970000000L, 2), (1, 1, 4580000000L, 3)], [(False, False, True, False), (False, False, True, False)]) The problem is that the cpuinfo for the second vcpu has it running on physical cpu 3, even though the affinity mask (within python and from taskset) says it can only run on physical cpu 2. The VM in question was originally started up running on pysical cpus 2 and 3, then I used the vcpupin/emulatorpin commands to only use physical cpu 2. Anyone got any ideas? I'm using libvirt-1.1.2 and libvirt-python-1.1.2 on a 3.4.82 kernel. Some more data: I have one VM running, taskset shows affinity as follows: root@compute-0:~# taskset -pac 7680 pid 7680's current affinity list: 2 pid 7681's current affinity list: 1-3 pid 7683's current affinity list: 2 pid 7684's current affinity list: 0 "virsh" has the following view: root@compute-0:~# virsh list Id Name State ---------------------------------------------------- 3 instance-0000001d running root@compute-0:~# virsh emulatorpin 3 emulator: CPU Affinity ---------------------------------- *: 2 root@compute-0:~# virsh vcpupin 3 VCPU: CPU Affinity ---------------------------------- 0: 2 1: 2 Thanks, Chris

[libvirt] [PATCH v5] migration: add support for migrateURI configuration
by Chen Fan 20 May '14

20 May '14

For now, we set the migration URI via command line '--migrate_uri' or construct the URI by looking up the dest host's hostname which could be solved by DNS automatically. But in cases the dest host have two or more NICs to reach, we may need to send the migration data over a specific NIC which is different from the automatically resloved one for some reason like performance, security, etc. thus we must explicitly specify the migrateuri in command line everytime, but it is too troublesome if there are many such hosts(and don't forget virt-manager). This patch adds a configuration file option on dest host to save the default value set which can be specified to a migration hostname or one of this host's addresses used for transferring data, thus user doesn't boring to specify it in command line everytime.

[libvirt] [PATCH] util: refactor virNetlinkCommand to fix several bugs / style problems
by Laine Stump 20 May '14

20 May '14

Inspired by a simpler patch from "Wangrui (K) <moon.wangrui(a)huawei.com>". A submitted patch pointed out that virNetlinkCommand() was doing an improper typecast of the return value from nl_recv() (int to unsigned), causing it to miss error returns, and that even after remedying that problem, virNetlinkCommand() was calling VIR_FREE() on the pointer returned from nl_recv() (*resp) even if nl_recv() had returned an error, and that in this case the pointer was verifiably invalid, as it was pointing to memory that had been allocated by libnl, but then freed prior to returning the error. While reviewing this patch, I noticed several other problems with this seemingly simple function (at least one of them as serious as the problem being reported/fixed by the aforementioned patch), and decided they all deserved to be fixed. Here is the list: 1) The return value from nl_recv() must be assigned to an int (rather than unsigned int) in order to detect failure. 2) When nl_recv() returns an error, the contents of *resp is invalid, and should be simply set to 0, *not* VIR_FREE()'d. 3) The first error return from virNetlinkCommand returns -EINVAL, incorrectly implying that the caller can expect the return value to be of the "-errno" variety, which is not true in any other case. 4) The 2nd error return returns directly with garbage in *resp. While the caller should never use *resp in this case, it's still good practice to set it to NULL. 5) For the next 5 (!!) error conditions, *resp will contain garbage, and virNetlinkCommand() will goto it's cleanup code which will VIR_FREE(*resp), almost surely leading to a segfault. In addition to fixing these 5 problems, this patch also makes the following two changes to make the function conform more closely to the style of other libvirt code: 1) Change the handling of return code from "named rc and defaulted to 0, but changed to -1 on error" to the more common "named ret and defaulted to -1, but changed to 0 on success". 2) Rename the "error" label to "cleanup", since the code that follows is executed in success cases as well as failure. --- src/util/virnetlink.c | 42 ++++++++++++++++++++---------------------- 1 file changed, 20 insertions(+), 22 deletions(-) diff --git a/src/util/virnetlink.c b/src/util/virnetlink.c index 0cf18f2..db8d59e 100644 --- a/src/util/virnetlink.c +++ b/src/util/virnetlink.c @@ -1,5 +1,5 @@ /* - * Copyright (C) 2010-2013 Red Hat, Inc. + * Copyright (C) 2010-2014 Red Hat, Inc. * Copyright (C) 2010-2012 IBM Corporation * * This library is free software; you can redistribute it and/or @@ -180,7 +180,7 @@ int virNetlinkCommand(struct nl_msg *nl_msg, uint32_t src_pid, uint32_t dst_pid, unsigned int protocol, unsigned int groups) { - int rc = 0; + int ret = -1; struct sockaddr_nl nladdr = { .nl_family = AF_NETLINK, .nl_pid = dst_pid, @@ -192,41 +192,39 @@ int virNetlinkCommand(struct nl_msg *nl_msg, int n; struct nlmsghdr *nlmsg = nlmsg_hdr(nl_msg); virNetlinkHandle *nlhandle = NULL; + int len = 0; if (protocol >= MAX_LINKS) { virReportSystemError(EINVAL, _("invalid protocol argument: %d"), protocol); - return -EINVAL; + goto cleanup; } nlhandle = virNetlinkAlloc(); if (!nlhandle) { virReportSystemError(errno, "%s", _("cannot allocate nlhandle for netlink")); - return -1; + goto cleanup; } if (nl_connect(nlhandle, protocol) < 0) { virReportSystemError(errno, _("cannot connect to netlink socket with protocol %d"), protocol); - rc = -1; - goto error; + goto cleanup; } fd = nl_socket_get_fd(nlhandle); if (fd < 0) { virReportSystemError(errno, "%s", _("cannot get netlink socket fd")); - rc = -1; - goto error; + goto cleanup; } if (groups && nl_socket_add_membership(nlhandle, groups) < 0) { virReportSystemError(errno, "%s", _("cannot add netlink membership")); - rc = -1; - goto error; + goto cleanup; } nlmsg_set_dst(nl_msg, &nladdr); @@ -237,8 +235,7 @@ int virNetlinkCommand(struct nl_msg *nl_msg, if (nbytes < 0) { virReportSystemError(errno, "%s", _("cannot send to netlink socket")); - rc = -1; - goto error; + goto cleanup; } memset(fds, 0, sizeof(fds)); @@ -253,26 +250,27 @@ int virNetlinkCommand(struct nl_msg *nl_msg, if (n == 0) virReportSystemError(ETIMEDOUT, "%s", _("no valid netlink response was received")); - rc = -1; - goto error; + goto cleanup; } - *respbuflen = nl_recv(nlhandle, &nladdr, - (unsigned char **)resp, NULL); - if (*respbuflen <= 0) { + len = nl_recv(nlhandle, &nladdr, (unsigned char **)resp, NULL); + if (len <= 0) { virReportSystemError(errno, "%s", _("nl_recv failed")); - rc = -1; + goto cleanup; } - error: - if (rc == -1) { - VIR_FREE(*resp); + + ret = 0; + cleanup: + if (ret < 0) { *resp = NULL; *respbuflen = 0; + } else { + *respbuflen = len; } virNetlinkFree(nlhandle); - return rc; + return ret; } static void -- 1.9.0

[libvirt] [libvirt-python][PATCH] Implement virDomain{Get, Set}Time APIs

While the setter can be generated automatically, the getter is not. However, it would be a lot easier if they both share the same logic: a python dictionary to represent the time: dict['seconds'] to represent seconds, and dict['nseconds'] to represent microseconds.
