[libvirt] [PATCH] macvtap: Fix error return values to -1 instead of 1
by Roopa Prabhu 20 Oct '11

20 Oct '11

From: Roopa Prabhu <roprabhu(a)cisco.com> Fixes some cases where 1 was being returned instead of -1. There are still some inconsistencies in the file with respect to what the return variable is initialized to. Can be fixed as a separate patch if needed. The scope of this patch is just to fix the return value 1. Did some basic sanity test.

[libvirt] [PATCH v3 0/4] Allow to make disk optional on migration
by Michal Privoznik 20 Oct '11

20 Oct '11

This is a 3rd version of patches [1]. Diff to v2 includes Daniel's review and some other improvements. The aim of these patches is to mark CDROM and floppy optional, thus they might get dropped during migration, domain startup, restore, etc. The granularity is set on disk level, so user can decide which cd-roms are important and which not. There are 3 levels of optionality: - mandatory - fail if missing for any reason (the default) - requisite - fail if missing on boot up, drop if missing on migrate/restore/revert - optional - drop if missing at any start attempt. To assign a disk one of these, just append 'on_missing' attribute to its <source>. If a domain is then eventually started (migrated, restored, whatever), we check for source path being accessible (currently only qemu driver is supported) from hypervisor's POV. This is done by virFileAccessibleAs() function. Currently, only uid+gid are considered. Ideally, this should be extended to SElinux labeling and cgroups. 1: https://www.redhat.com/archives/libvir-list/2011-October/msg00032.html Michal Privoznik (4): conf: Introduce optional on_missing attribute for cdrom and floppy util: Create virFileAccessibleAs function qemu: implement on_missing on_missing: Emit event on disk source dropping daemon/remote.c | 37 ++++++++++ docs/formatdomain.html.in | 26 ++++++- docs/schemas/domaincommon.rng | 22 +++++- examples/domain-events/events-c/event-test.c | 27 +++++++- examples/domain-events/events-python/event-test.py | 4 + include/libvirt/libvirt.h.in | 28 +++++++ python/libvirt-override-virConnect.py | 9 +++ python/libvirt-override.c | 51 +++++++++++++ src/conf/domain_conf.c | 43 ++++++++++- src/conf/domain_conf.h | 11 +++ src/conf/domain_event.c | 50 +++++++++++++ src/conf/domain_event.h | 7 ++ src/libvirt_private.syms | 4 + src/qemu/qemu_domain.c | 73 +++++++++++++++++++ src/qemu/qemu_domain.h | 4 + src/qemu/qemu_process.c | 4 + src/remote/remote_driver.c | 34 +++++++++ src/remote/remote_protocol.x | 9 ++- src/remote_protocol-structs | 5 ++ src/util/util.c | 76 ++++++++++++++++++++ src/util/util.h | 3 + .../qemuxml2xmlout-disk-cdrom-empty.xml | 31 ++++++++ 22 files changed, 548 insertions(+), 10 deletions(-) create mode 100644 tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-cdrom-empty.xml -- 1.7.3.4

[libvirt] [PATCH 1/2] Fix occasional container creation failure due to misuse of grantpt
by Serge E. Hallyn 20 Oct '11

20 Oct '11

glibc's grantpt and ptsname cannot be used on a fd for a pty not in /dev/pts. The lxc controller tries to do just that. So if you try to start a container on a system where /dev/pts/0 is not available, it will fail. You can make this happen by opening a terminal on /dev/pts/0, and doing 'sleep 2h & disown; exit'. To fix this, I call the virFileOpenTtyAt() from a forked task in a new mount ns, and first mount the container's /dev/pts onto /dev/pts. (Then the opened fd must be passed back to the lxc driver). Another solution would be to just do it all by hand without grantpt and ptsname.

[libvirt] [PATCH V2 00/10] Make inner workings of nwfilters more flexible + extensions
by Stefan Berger 20 Oct '11

20 Oct '11

The following series of patches re-does some of the inner workings of nwfilters with the goal to enable users to write filters that have other than the system-known chains supported right now ('root','arp','rarp','ipv4' and 'ipv6'). Ideally users should be able to provide a chain name in the chains XML attribute and either be able to jump to it as an 'action' or have the chain created automatically as it is the case right now for those chains enumerated before. The latter is now added in this patch series as well. I am first introducing internal priorities for the chains mentioned above so that their creation can be made more flexible -- currently their creation and the order in which they are accessed is hardcoded. This largely does away with the hardcoded stuff. All assigned priorities have negative values. Later on the priorities for the chains are made accessible via an XML attribute. Further, filters will be automatically accessed from the (ebtables) interface 'root' chain using the prefix of the name of the chain. As an example, the following filter will be accessed from the root chain for 'arp' packets since its name 'arp-xyz' has the prefix 'arp'. <filter name='test-arp-xyz' chain='arp-xyz' priority='-650'> <uuid>94abeecc-c956-0ac8-1f49-a06ee8995688</uuid> <rule action='accept' direction='out' priority='100'> <arp opcode='Request_Reverse' arpsrcmacaddr='$MAC' arpdstmacaddr='$MAC' arpsrcipaddr='0.0.0.0' arpdstipaddr='0.0.0.0'/> </rule> <rule action='accept' direction='inout' priority='500'/> </filter> In another step the priorities of rules is extended to also allow negativ values. This then allows the creation of rules and chains in the interface 'root' chain to be mixed so that the following layout becomes possible: Bridge chain: libvirt-I-vnet0, entries: 6, policy: ACCEPT -p IPv4 -j I-vnet0-ipv4 -p ARP -j I-vnet0-arp -p ARP -j ACCEPT -p 0x8035 -j I-vnet0-rarp -p 0x835 -j ACCEPT -j DROP In the above list of rules the '-p ARP -j ACCEPT' can now be found in between the 'jumps' to protocol-specific chains, which allows for more efficient rule evaluation. I did testing with the test cases in libvirt-tck as well as those in the tests/ directory and did not see any regressions. Regards, Stefan

Hello, I think it's time to plan for the next release, it may be a bit late to target the end of the month but I would think entering freeze around Friday 28 allowing for a release of 0.9.7 around Nov 4th should give people enough time to get reviews and push feeatures in, so unless there is an objection, let's plan to enter feature freeze at the end of next week !
