[libvirt] [libvirt-test-API][PATCH] Fix utils.exec_cmd output problem
by Jincheng Miao 27 Nov '13

27 Nov '13

The 'out' returned from exec_cmds is not 'None' type if stderr occurs, it is because utils pass 'subprocess.PIPE' to stdout to open this subprocess. "Similarly, to get anything other than None in the result tuple, you need to give stdout=PIPE and/or stderr=PIPE too." (see http://docs.python.org/2/library/subprocess.html#module-subprocess) Finally, make out equals to err when stderr happened. --- utils/utils.py | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/utils/utils.py b/utils/utils.py index 147c1ef..2248ce1 100644 --- a/utils/utils.py +++ b/utils/utils.py @@ -404,14 +404,12 @@ def exec_cmd(command, sudo=False, cwd=None, infile=None, outfile=None, shell=Fal command = ["sudo"] + command if infile == None: infile = subprocess.PIPE - if outfile == None: - outfile = subprocess.PIPE p = subprocess.Popen(command, shell=shell, close_fds=True, cwd=cwd, stdin=infile, stdout=outfile, stderr=subprocess.PIPE) (out, err) = p.communicate(data) if out == None: - # Prevent splitlines() from barfing later on - out = "" + # Because stderr is PIPE, err will not be None, and can be splitlines. + out = err return (p.returncode, out.splitlines()) def remote_exec_pexpect(hostname, username, password, cmd): -- 1.8.3.1

[libvirt] [PATCH] storage: don't read storage volumes in nonblock mode
by Eric Blake 26 Nov '13

26 Nov '13

Commit 348b4e2 introduced a potential problem (thankfully not in any release): we are attempting to use virFileReadHeaderFD() on a file that was opened with O_NONBLOCK. While this shouldn't be a problem in practice (because O_NONBLOCK typically doesn't affect regular or block files, and fifos and sockets cannot be storage volumes), it's better to play it safe to avoid races from opening an unexpected file type while also avoiding problems with having to handle EAGAIN while read()ing.

Libvirt is already converting a user's rate of bytes/period into the qemu parameters, defaulting to 1 second as its default period. Am I correct that as long as libvirt specified both rate AND period, then this change has no impact (and that the 7% change occurs if you specify period while leaving max-bytes alone)? Or is this an ABI change where libvirt will have to be taught to be smart enough to know whether it is old qemu or new qemu to adjust how libvirt does its calculations when converting the user's rate into qemu terms? -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org

[libvirt] [PATCH v2] Pin guest to memory node on NUMA system
by Shivaprasad G Bhat 26 Nov '13

26 Nov '13

Version 2: Fixed the string formatting errors in v1. Version 1: The patch contains the fix for defect 1009880 reported at redhat bugzilla. The root cause is, ever since the subcpusets(vcpu,emulator) were introduced, the paren cpuset cannot be modified to remove the nodes that are in use by the subcpusets. The fix is to break the memory node modification into three steps as to assign new nodes into the parent first. Change the nodes in the child nodes. Then remove the old nodes on the parent node.
