[libvirt] How to add custom tag to the libvirt xml file for a new feature of the VM
by Yashwanth K P 05 Jun '12

05 Jun '12

Hello, I am working on libvirt development and I wanted to add a custom tag to the libvirt xml to add a new feature to the VM. I am having trouble getting started with this. It would be really helpful if you can help me get started with this and guide me on what part of the source code that has to be modified to achieve the goal. Thanks in advance. Regards, Yashwanth KP

[libvirt] [PATCH] Convert 'raw MAC address' usages to use virMacAddr
by Stefan Berger 05 Jun '12

Introduce new members in the virMacAddr 'class': - virMacAddrSet: set virMacAddr from a virMacAddr - virMacAddrSetRaw: setting virMacAddr from raw 6 byte MAC address buffer - virMacAddrGetRaw: writing virMacAddr into raw 6 byte MAC address buffer - virMacAddrCmp: comparing two virMacAddr - virMacAddrCmpRaw: comparing a virMacAddr with a raw 6 byte MAC address buffer then replace raw MAC addresses by replacing - 'unsigned char *' with virMacAddrPtr - 'unsigned char ...

[libvirt] [PATCH] Fix for parallel port passtrough for QEMU
by Beat.Joerg＠ssatr.ch 04 Jun '12

04 Jun '12

Hi As requested by Dave, I send this to the list. I came across a bug that the command line generated for passtrough of the host parallel port /dev/parport0 by libvirt for QEMU is incorrect. It currently produces: -chardev tty,id=charparallel0,path=/dev/parport0 -device isa-parallel,chardev=charparallel0,id=parallel0 The first parameter is "tty". It sould be "parport". If I launch qemu with -chardev parport,... it works as expected. I have already filled a bug report ( https://bugzilla.redhat.com/show_bug.cgi?id=823879 ), the topic was already on the list some months ago: https://www.redhat.com/archives/libvirt-users/2011-September/msg00095.html Not sure if this is fix is very clean, but for my case it works. Perhaps it should also be checked if similar problems / patches are required for other chardev backends. Kind regards Beat diff -Naur libvirt-0.9.4.orig/src/qemu/qemu_command.c libvirt-0.9.4/src/qemu/qemu_command.c --- libvirt-0.9.4.orig/src/qemu/qemu_command.c 2012-05-22 13:40:16.788633656 +0200 +++ libvirt-0.9.4/src/qemu/qemu_command.c 2012-05-22 13:52:18.453608557 +0200 @@ -2357,8 +2357,14 @@ break; case VIR_DOMAIN_CHR_TYPE_DEV: - virBufferAsprintf(&buf, "tty,id=char%s,path=%s", alias, - dev->data.file.path); + if (STRPREFIX(dev->data.file.path, "/dev/parport")) { + virBufferAsprintf(&buf, "parport,id=char%s,path=%s", alias, + dev->data.file.path); + } + else { + virBufferAsprintf(&buf, "tty,id=char%s,path=%s", alias, + dev->data.file.path); + } break; case VIR_DOMAIN_CHR_TYPE_FILE:

[libvirt] [PATCH] command: avoid deadlock on EPIPE situation
by Eric Blake 04 Jun '12

04 Jun '12

It is possible to deadlock libvirt by having a domain with XML longer than PIPE_BUF, and by writing a hook script that closes stdin early. This is because libvirt was keeping a copy of the child's stdin read fd open, which means the write fd in the parent will never see EPIPE (remember, libvirt should always be run with SIGPIPE ignored, so we should never get a SIGPIPE signal). Since there is no error, libvirt blocks waiting for a write to complete, even though the only reader is also libvirt. The solution is to ensure that only the child can act as a reader before the parent does any writes; and then dealing with the fallout of dealing with EPIPE. Thankfully, this is not a security hole - since the only way to trigger the deadlock is to install a custom hook script, anyone that already has privileges to install a hook script already has privileges to do any number of other equally disruptive things to libvirt; it would only be a security hole if an unprivileged user could install a hook script to DoS a privileged user. * src/util/command.c (virCommandRun): Close parent's copy of child read fd earlier. (virCommandProcessIO): Don't let EPIPE be fatal; the child may be done parsing input. * tests/commandhelper.c (main): Set up a SIGPIPE situation. * tests/commandtest.c (test20): Trigger it. * tests/commanddata/test20.log: New file. --- I tested this by using just the changes to 'tests/', and was able to trigger deadlock in 100% of my testing with the buffer lengths shown here. src/util/command.c | 22 +++++++++++++--------- tests/commanddata/test20.log | 13 +++++++++++++ tests/commandhelper.c | 6 ++++++ tests/commandtest.c | 42 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 74 insertions(+), 9 deletions(-) create mode 100644 tests/commanddata/test20.log diff --git a/src/util/command.c b/src/util/command.c index ba43078..52a457c 100644 --- a/src/util/command.c +++ b/src/util/command.c @@ -1738,7 +1738,7 @@ virCommandProcessIO(virCommandPtr cmd, int *inpipe) break;
