Hi, I've been trying out a bash autocompletion file by Geoff Low (slight hack by me, don't blame him for my hack), and it's working pretty nicely. I'm not sure where to put it in the git tree, but it seems like it'd be nice to have upstream? thanks, -serge ==================================================== #!/bin/bash ############################################################################# # # virsh bash completion # Author: Geoff Low (glow(a)cmedresearch.com) # ############################################################################ VIRSH=$(which virsh) function get_main_option_list { # assume options are specified as [--option1 | --option2 | ...] OPTIONS=$(${VIRSH} help | grep '|' | sed -e 's/.*\[$.*$\]/\1/g;s/|//g') } function get_option_list { # get the options for a choice local option=$1; # assume options are specified as [--option1 | --option2 | ...] OPTIONS=$(${VIRSH} help ${option} 2> /dev/null | grep '|' | sed -e 's/.*\[$.*$\]/\1/g;s/|//g') } function _virsh_complete() { local cur prev opts COMPREPLY=() cur="${COMP_WORDS[COMP_CWORD]}" prev="${COMP_WORDS[COMP_CWORD-1]}" cnxn="" i=0 while [[ $i -lt $COMP_CWORD ]]; do if [ ${COMP_WORDS[i]} = "-c" ]; then tgt=`echo ${COMP_LINE} | sed -e 's/^.* -c $[^ \t]*$.*$/\1/'` cnxn="-c $tgt" break fi let i++ done if [ ! -z $tgt ]; then if [ $COMP_CWORD -eq 5 ]; then prev="${COMP_WORDS[0]}" fi fi _all_domains=$(${VIRSH} ${cnxn} --q list --all 2> /dev/null | grep -E "(running|shut off)$" | awk '{print $2,$3}') all_domains=$(echo "$_all_domains" | cut -d " " -f 1) all_networks=$(${VIRSH} --q net-list --all 2> /dev/null | grep 'active' | cut -d " " -f 1) live_domains=$(echo "$_all_domains" | grep -E "running$" | awk '{print $1}') shutoff_domains=$(echo "$_all_domains" | grep -E "shut$" | awk '{print $1}') case "${prev}" in virsh | --help) get_main_option_list ALL_OPTS=$(${VIRSH} -q help 2> /dev/null | sed '1,2d' | awk '{print $1}') COMPREPLY=( $(compgen -W "$OPTIONS $ALL_OPTS" -- ${cur}) ) ;; list) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS" -- ${cur}) ) ;; autostart | dominfo | domuuid | domid | dominfo | domname | dumpxml | setmem ) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $all_domains" -- ${cur}) ) ;; start | undefine) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $shutoff_domains" -- ${cur}) ) ;; create | define) get_option_list ${prev} xml_files=$(ls *.xml) COMPREPLY=( $(compgen -W "$OPTIONS $xml_files" -- ${cur}) ) ;; shutdown | domstate | console | destroy | reboot | save | suspend | resume | vcpuinfo | vncdisplay) get_option_list ${prev} COMPREPLY=( $(compgen -W "$OPTIONS $live_domains" -- ${cur}) ) ;; connect) get_option_list ${prev} URI_TEMPLATES="xen:// qemu:// test:// xen+ssh:// test+tcp:// qemu+unix:// qemu+tls:// qemu+ssh://" COMPREPLY=( $(compgen -W "$OPTIONS $URI_TEMPLATES" -- ${cur}) ) ;; *) COMPREPLY=( $(compgen -f -- ${cur}) ) return 0 ;; esac } complete -F _virsh_complete virsh

[libvirt] [PATCH 1/4] add a qemu-specific event register API, to passthough the new events come from qemu

by shaohef＠linux.vnet.ibm.com

From: ShaoHe Feng <shaohef(a)linux.vnet.ibm.com> Basically, this feature can go along with qemu monitor passthrough. That way, if we use new commands in the monitor that generate new events, we want some way to receive those new events too.

[libvirt] Build issue with libvirt 0.9.8

by Christophe Fergeau

Hi, When building libvirt 0.9.8 with jhbuild, I have now reproduced twice some issue during the build. Namely, after successfully building and installing libvirt 0.9.8, when I try to run virsh, I get: virsh: /home/teuf/jhbuild-boxes/opt/lib64/libvirt.so.0: version `LIBVIRT_PRIVATE_0.9.7' not found (required by /home/teuf/jhbuild-boxes/opt/lib64/libvirt-qemu.so.0) This happens when I start from a clean prefix (no libvirt in it), then I install 0.9.7, and then I try to install 0.9.8 on top of it. If I rebuild libvirt-0.9.8 once more this goes away, so this is not a blocking problem for me. I have checked that libvirt-qemu.so.0 is the 0.9.8 version, I have looked in the build logs and in Makefile.am and everything looks correct to me, so I was wondering if anyone had any explanation for this behaviour. Once again, it's easy to workaround so it's not a big issue, but I'm mentioning it in case there would something obvious I missed. I put the build logs at http://people.gnome.org/~teuf/libvirt-0.9.7 and http://people.gnome.org/~teuf/libvirt-0.9.8 Christophe

[libvirt] [PATCH 0/8 v5] Summary on block IO throttle

by Lei Li

Changes since V3 - Use virTypedParameterPtr instead of specific struct in libvirt pulic API. - Relevant changes to remote driver, qemu driver, python support and virsh. Changes since V2 - Implement the Python binding support for setting blkio throttling. - Implement --current --live --config options support to unify the libvirt API. - Add changes in docs and tests. - Some changes suggested by Adam Litke, Eric Blake, Daniel P. Berrange. - Change the XML schema. - API name to virDomain{Set, Get}BlockIoTune. - Parameters changed to make them more self-explanatory. - virsh command name to blkdeviotune. - And other fixups. Changes since V1 - Implement the support to get the block io throttling for a device as read only connection - QMP/HMP. - Split virDomainBlockIoThrottle into two separate functions virDomainSetBlockIoThrottle - Set block I/O limits for a device - Requires a connection in 'write' mode. - Limits (info) structure passed as an input parameter virDomainGetBlockIoThrottle - Get the current block I/O limits for a device - Works on a read-only connection. - Current limits are written to the output parameter (reply). - And Other fixups suggested by Adam Litke, Daniel P. Berrange. - For dynamically allocate the blkiothrottle struct, I will fix it when implement --current --live --config options support. Today libvirt supports the cgroups blkio-controller, which handles proportional shares and throughput/iops limits on host block devices. blkio-controller does not support network file systems (NFS) or other QEMU remote block drivers (curl, Ceph/rbd, sheepdog) since they are not host block devices. QEMU I/O throttling works with all types of drive and can be applied independently to each drive attached to a guest and supports throughput/iops limits. To help add QEMU I/O throttling support to libvirt, we plan to complete it with add new API virDomain{Set, Get}BlockIoThrottle(), new command 'blkdeviotune' and Python bindings. Notes: Now all the planed features were implemented (#1#2 were implemented by Zhi Yong Wu), the previous comments were all fixed up too. And the qemu part patches have been accepted upstream and are expected to be part of the QEMU 1.1 release, git tree from Zhi Yong: http://repo.or.cz/w/qemu/kevin.git/shortlog/refs/heads/block 1) Enable the blkio throttling in xml when guest is starting up. Add blkio throttling in xml as follows: <disk type='file' device='disk'> ... <iotune> <total_bytes_sec>nnn</total_bytes_sec> ... </iotune> ... </disk> 2) Enable blkio throttling setting at guest running time. virsh blkdeviotune <domain> <device> [--total_bytes_sec<number>] [--read_bytes_sec<number>] \ [--write_bytes_sec<number>] [--total_iops_sec<number>] [--read_iops_sec<number>] [--write_iops_sec<number>] 3) The support to get the current block i/o throttling for a device - HMP/QMP. virsh blkiothrottle <domain> <device> total_bytes_sec: read_bytes_sec: write_bytes_sec: total_iops_sec: read_iops_sec: write_iops_sec: 4) Python binding support for setting blkio throttling. 5) --current --live --config options support to unify the libvirt API. virsh blkdeviotune <domain> <device> [--total_bytes_sec <number>] [--read_bytes_sec <number>] [--write_bytes_sec <number>] [--total_iops_sec <number>] [--read_iops_sec <number>] [--write_iops_sec <number>] [--config] [--live] [--current] daemon/remote.c | 108 +++++++ docs/formatdomain.html.in | 31 ++ docs/schemas/domaincommon.rng | 24 ++ include/libvirt/libvirt.h.in | 70 ++++ python/generator.py | 2 + python/libvirt-override-api.xml | 16 + python/libvirt-override.c | 179 +++++++++++ src/conf/domain_conf.c | 101 ++++++- src/conf/domain_conf.h | 12 + src/driver.h | 20 ++ src/libvirt.c | 145 +++++++++ src/libvirt_public.syms | 2 + src/qemu/qemu_command.c | 33 ++ src/qemu/qemu_driver.c | 338 ++++++++++++++++++++ src/qemu/qemu_monitor.c | 36 ++ src/qemu/qemu_monitor.h | 22 ++ src/qemu/qemu_monitor_json.c | 185 +++++++++++ src/qemu/qemu_monitor_json.h | 10 + src/qemu/qemu_monitor_text.c | 164 ++++++++++ src/qemu/qemu_monitor_text.h | 10 + src/remote/remote_driver.c | 96 ++++++ src/remote/remote_protocol.x | 26 ++- src/remote_protocol-structs | 24 ++ src/util/xml.h | 2 + .../qemuxml2argv-blkdeviotune.args | 4 + .../qemuxml2argvdata/qemuxml2argv-blkdeviotune.xml | 37 +++ tests/qemuxml2argvtest.c | 1 + tests/qemuxml2xmltest.c | 1 + tools/virsh.c | 240 ++++++++++++++ tools/virsh.pod | 23 ++ 30 files changed, 1958 insertions(+), 4 deletions(-) -- Lei

[libvirt] [PATCH v2 0/6] Console coruption with two or more clients series

by Peter Krempa

This series fixes anoying console corruption if two clients try to connect at same time to the console. The current state of this is, that two/more of threads compete for the data from the PTY. This causes that each of the consoles get scrambled and unusable. These patches add mutual exclusion for opening consoles with two different approaches and a option to terminate existing console streams. A sample implementation is done using qemu driver, but i'll add more of them if this will be OK. (They're basicaly the same as in qemu). For convinience, to review these patches: git checkout -b console_corruption 8d16201fe0e63afb5416a8eb7c6478f582ccccc0 git pull git://aeon.pipo.sk/libvirt.git console_dup (The machine should be up most of time) Peter Peter Krempa (6): Add flags for virDomainOpenConsole virsh: add support for VIR_DOMAIN_CONSOLE_FORCE flag fdstream: Emit stream abort callback even if poll() doesnt. fdstream: Add internal callback on stream close util: Add helpers for safe domain console operations qemu: Add ability to abort existing console while creating new one configure.ac | 37 +++- include/libvirt/libvirt.h.in | 12 +- src/Makefile.am | 5 +- src/fdstream.c | 95 +++++++++- src/fdstream.h | 11 + src/libvirt_private.syms | 6 + src/qemu/qemu_domain.c | 5 + src/qemu/qemu_domain.h | 3 + src/qemu/qemu_driver.c | 21 ++- src/util/domain_safe_console.c | 399 ++++++++++++++++++++++++++++++++++++++++ src/util/domain_safe_console.h | 28 +++ tools/console.c | 5 +- tools/console.h | 3 +- tools/virsh.c | 18 ++- 14 files changed, 614 insertions(+), 34 deletions(-) create mode 100644 src/util/domain_safe_console.c create mode 100644 src/util/domain_safe_console.h -- 1.7.3.4

[libvirt] Using virtEvents in macvtap setup code

by Dirk Herrendoerfer

Hi all, I'm trying to get libvirt to re-associate lost connections when a vepa connection is lost due to a switch error, or lldpad restart. My take was to use the virtEvent infrastructure to poll for messages on a netlink socket and then restart the association if the message indicates that a link came back up. I ran into a problem, that if I start the polling netlink event from the daemon thread I would get the file events an the netlink messages, but I cannot configure the event handler because the rpc client threads and the daemon do not share the same address space. Is there a way to get file events in the VMs setup code so I can register a callback at VM initialization time to receive netlink messages and restart association if needed ? Best regards, D.Herrendoerfer <herrend at de dot ibm dot com > <d.herrendoerfer at herrendoerfer dot name>

[libvirt] [PATCH 0/5 v3] Interface pools and passthrough mode

by Shradha Shah

Interface Pools and Passthrough mode: Current Method: The passthrough mode uses a macvtap direct connection to connect each guest to the network. The physical interface to be used is picked from among those listed in <interface> sub elements of the <forward> element. The current specification for <forward> extends to allow 0 or more <interface> sub-elements: Example: <forward mode='passthrough' dev='eth10'/> <interface dev='eth10'/> <interface dev='eth12'/> <interface dev='eth18'/> <interface dev='eth20'/> </forward> However with an ethernet card with 64 VF's or more, the above method gets tedious on the system. On the other hand, just parameterizing a string (eth%d) is inadequate, eg, when there are multiple non-contiguous ranges. Proposed Method: The 4 patches provided: i) Introduce a new element 'pf' to implicitly create an interface pool of all the Virtual Functions attached to the specified Physical Function. ii) Modify the networkAllocateActualDevice, networkNotifyActualDevice and networkReleaseActualDevice API to use the above mentioned interface pool in the passthrough mode. iii) Allow virsh net-dumpxml to use an option --inactive to differentiate between explicit and implicit interface pools Hence Libvirt will now support both the methods mentioned below: * Explicit interface list. App inputs: <forward mode='passthrough'> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> libvirt does not change XML * Automatically interface list from PF. App inputs: <forward mode='passthrough'> <pf dev='eth0'/> </forward> libvirt expands XML to be <forward mode='passthrough'> <pf dev='eth0'/> <interface dev='eth10'/> <interface dev='eth11'/> <interface dev='eth12'/> <interface dev='eth13'/> </forward> In the above case we need to differentiate between the implicit and explicit interface pool, which can be done by comparing the dumpxml from active and inactive domains. This will need the addition of the flag VIR_NETWORK_XML_INACTIVE to virNetworkGetXMLDesc(). This patch series supports the use of option --inactive with virsh net-dumpxml. Shradha Shah (5): Added function pciSysfsFile to enable access to the PCI SYSFS files. Added Function virNetDevGetVirtualFunctions Adding the element pf to network xml. Functionality to implicitly get interface pool from SR-IOV PF.

[libvirt] [PATCH] Change security driver APIs to use virDomainDefPtr instead of virDomainObjPtr

by Daniel P. Berrange

From: "Daniel P. Berrange" <berrange(a)redhat.com> When sVirt is integrated with the LXC driver, it will be neccessary to invoke the security driver APIs using only a virDomainDefPtr since the lxc_container.c code has no virDomainObjPtr available. Aside from two functions which want obj->pid, every bit of the security driver code only touches obj->def. So we don't need to pass a virDomainObjPtr into the security drivers, a virDomainDefPtr is sufficient. Two functions also gain a 'pid_t pid' argument. * src/qemu/qemu_driver.c, src/qemu/qemu_hotplug.c, src/qemu/qemu_migration.c, src/qemu/qemu_process.c, src/security/security_apparmor.c, src/security/security_dac.c, src/security/security_driver.h, src/security/security_manager.c, src/security/security_manager.h, src/security/security_nop.c, src/security/security_selinux.c, src/security/security_stack.c: Change all security APIs to use a virDomainDefPtr instead of virDomainObjPtr --- src/qemu/qemu_driver.c | 10 +- src/qemu/qemu_hotplug.c | 28 ++-- src/qemu/qemu_migration.c | 12 +- src/qemu/qemu_process.c | 24 ++-- src/security/security_apparmor.c | 136 ++++++++++---------- src/security/security_dac.c | 91 +++++++------- src/security/security_driver.h | 36 +++--- src/security/security_manager.c | 40 +++--- src/security/security_manager.h | 36 +++--- src/security/security_nop.c | 36 +++--- src/security/security_selinux.c | 260 +++++++++++++++++++------------------- src/security/security_stack.c | 44 ++++--- 12 files changed, 381 insertions(+), 372 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 6cfdd1d..6e001ce 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -3096,7 +3096,7 @@ qemuDomainScreenshot(virDomainPtr dom, } unlink_tmp = true;

[libvirt] [PATCH 0/6] nwfilter: Enable access to variables via iterator or index

by Stefan Berger

This patch enables access to variables in filters using indep. iterators ($TEST[$@2]) or via index ($TEST[1]). Three test cases are added that are also being used for libvirt-TCK to check that the instantiation of the filtering rules is correct. Regards, Stefan
