[libvirt] [PATCH 00/14] Add a virtlockd lock manager daemon
by Daniel P. Berrange 06 Dec '11

06 Dec '11

The lock manager infrastructure we recently added to QEMU only has two possible drivers at this time, 'nop' and 'sanlock'. The former does absolutely nothing, while the latter requires a 3rd party package installed and is a little heavy on disk I/O and storage requirements. This series adds a new daemon 'virtlockd' which is intended to be enabled by default on all hosts running 'libvirtd'. This daemon provides a service for disk locking based on the traditional fcntl() lock primitives. There is a new libvirt manager plugin which talks to this daemon over RPC. The reason for doing the locks in a separate process is that we want the locks to remain active, even if libvirtd crashes, or is restarted. The virtlockd daemon has this one single job so should be pretty reliable and selfcontained. This patch series really benefits from the new RPC APIs, requiring minimal code for the new daemon / client At this time, virtlockd does not lock the actual disk files, but instead creates a lockspace & leases under /var/lib/libvirt/lockd. The lockspace we use for disks is named org.libvirt.lockd.files, and lease names are based on a SHA256 checksum of the fully qualified disk name. eg /var/lib/libvirt/lockd/org.libvirt.lockd.files/adf94fc33a24da1abff7dd7374a9919bb51efee646da8c3ac464c10cd59750bd These leases are all zero-bytes long and no I/O is ever performed on them, only fcntl() is used. So there is material overhead. Whenever creating or deleting leases, we first acquire a lock on /var/lib/libvirt/lockd/org.libvirt.lockd.files/org.libvirt.lockd.index A non-root virtlockd will instead use $HOME/.libvirt/lockd By default we gain protection out of the box against - Starting two guests on the same host with the same disk image not marked with <shareable/> - libvirtd getting confused and forgetting a guest, allowing it to be started for a 2nd time If the admin mounts a shared filesytem (eg NFS) on /var/lib/libvirt/lockd then this protection is extended across all hosts sharing that mount volume. As part of this series, I also introduce support for systemd services for libvirtd and libvir-guests.

[libvirt] [PATCH 00/10] Console coruption with two or more clients series
by Peter Krempa 06 Dec '11

06 Dec '11

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 libvirt iohelpers are spawned on the same time that compete for data from the pty. This causes that each of the consoles get scrambled and unusable. Patches fdstream: Emit stream abort callback even if poll() doesnt. virnetclientstream: Propagate stream error messages to callback daemon: Subscribe the stream event callback for error events. add the ability to abort a stream from the daemon side. fdstream: Add internal function to check if a fdstream is open This patch adds a helper function that checks internally if a fdstream is open and working. virsh: fix console stream error reporting Add flags for virDomainOpenConsole virsh: add support for VIR_DOMAIN_CONSOLE_FORCE flag This patches add instrumentation to virsh that supports the new ability to abort streams from the daemon side and adapts the console callback to handle this. These patches also add a new flag set for virDomainOpenConsole API call that allow users to control the if the existing console connection should be left in place or killed in favor of the new one qemu: Add ability to abort existing console while creating new one lxc: Add ability to abort existing console when creating a new one uml: Add ability to abort existing console when creating a new one These patches modify the hypervisor drivers so that they are aware of existing console connections and refuse to create a new one (or kill the old). The xen driver also supports console in a similar way like the previously mentioned drivers, but lacks the means to store a stream reference permanently. I'll look in if it's possible to modify this driver to support this new functionality.

[libvirt] [RFC PATCH 0/5] Support online resizing of block devices.
by Osier Yang 29 Nov '11

29 Nov '11

This patch series introduce new API "virDomainBlockResize" to expose qemu monitor command "block_size", which is for resizing the a block device while the domain is running. The prototype for the new API is: int virDomainBlockResize (virDomainPtr dom, const char *path, unsigned long long size, unsigned int flags) * "@path" is the absolute path of the block device, which can be extraced from domain xml. * The units for "@size" is kilobytes, which might be not quite properly. (qemu HMP uses Megabytes as the default units, QMP uses Bytes as the default units, so it means we need to divice "@size" by 1024 for HMP, and multiply "@size" by 1024 for QMP. On the other hand, we need to check the overflowing). Any ideas on this is welcomed. * "@flags" is unused currently. [PATCH 1/5] block_resize: Define the new API [PATCH 2/5] block_resize: Wire up the remote protocol [PATCH 3/5] block_resize: Implement qemu monitor functions [PATCH 4/5] block_resize: Implement qemu driver method [PATCH 5/5] block_resize: Expose the new API to virsh

[libvirt] [PATCH v4 00/13] Implement keepalive protocol for libvirt RPC
by Jiri Denemark 24 Nov '11

24 Nov '11

This patchset can also be found at https://gitorious.org/~jirka/libvirt/jirka-staging/commits/keepalive This allows us to detect broken connections between server and client without waiting for TCP timeout and dead deamon/client. By default a connection is considered broken after about 30 seconds of no messages received from remote party. After that period, the connection is automatically closed. The main reason for implementing this is that peer-to-peer migration can now be canceled when a connection between source and target breaks. Although this will really work only after qemu fixes migrate_cancel command so that it doesn't block when outgoing TCP buffers are full. Version 4 addresses comments from Daniel and Matthias. Although most of the patches were already (conditionally) acked, I'm sending all of them to provide a complete picture of the change. Patches that were already acked are explicitly marked so in the Notes section so anyone can just skip them if they like. Jiri Denemark (13): Define keepalive protocol Implement common keepalive handling Introduce virConnectSetKeepAlive virsh: Always run event loop Implement keepalive protocol in libvirt daemon Add support for non-blocking calls in client RPC Add support for async close of client RPC socket Implement keepalive protocol in remote driver Introduce virConnectIsAlive API Implement virConnectIsAlive in all drivers Add keepalive support into domain-events examples qemu: Add support for keepalive messages during p2p migration qemu: Cancel p2p migration when connection breaks .gitignore | 1 + daemon/libvirtd.aug | 5 + daemon/libvirtd.c | 15 + daemon/libvirtd.conf | 25 ++ daemon/libvirtd.h | 1 + daemon/remote.c | 48 ++- examples/domain-events/events-c/event-test.c | 9 +- examples/domain-events/events-python/event-test.py | 4 +- include/libvirt/libvirt.h.in | 5 + po/POTFILES.in | 1 + src/Makefile.am | 20 +- src/driver.h | 8 + src/esx/esx_driver.c | 18 + src/hyperv/hyperv_driver.c | 18 + src/libvirt.c | 93 ++++ src/libvirt_internal.h | 10 +- src/libvirt_private.syms | 2 + src/libvirt_public.syms | 2 + src/libxl/libxl_driver.c | 8 + src/lxc/lxc_driver.c | 7 + src/openvz/openvz_driver.c | 7 + src/phyp/phyp_driver.c | 18 + src/probes.d | 12 + src/qemu/libvirtd_qemu.aug | 2 + src/qemu/qemu.conf | 22 + src/qemu/qemu_conf.c | 11 + src/qemu/qemu_conf.h | 3 + src/qemu/qemu_driver.c | 6 + src/qemu/qemu_migration.c | 43 ++- src/qemu/test_libvirtd_qemu.aug | 6 + src/remote/remote_driver.c | 70 +++ src/remote/remote_protocol.x | 2 +- src/rpc/virkeepalive.c | 448 ++++++++++++++++++++ src/rpc/virkeepalive.h | 56 +++ src/rpc/virkeepaliveprotocol.x | 7 + src/rpc/virnetclient.c | 428 ++++++++++++++++--- src/rpc/virnetclient.h | 6 + src/rpc/virnetserver.c | 22 + src/rpc/virnetserver.h | 5 + src/rpc/virnetserverclient.c | 143 ++++++- src/rpc/virnetserverclient.h | 7 + src/test/test_driver.c | 6 + src/uml/uml_driver.c | 7 + src/util/event.c | 6 +- src/vbox/vbox_tmpl.c | 6 + src/vmware/vmware_driver.c | 7 + src/xen/xen_driver.c | 8 + src/xenapi/xenapi_driver.c | 12 + tools/console.c | 17 +- tools/virsh.c | 31 ++ 50 files changed, 1621 insertions(+), 103 deletions(-) create mode 100644 src/rpc/virkeepalive.c create mode 100644 src/rpc/virkeepalive.h create mode 100644 src/rpc/virkeepaliveprotocol.x -- 1.7.7.1

[libvirt] bug: try to take disk snapshot for LVM2 Volume
by MATSUDA, Daiki 21 Nov '11

21 Nov '11

I tried the new snapshot function implemented by Eric Blake. It works very well for QCOW2 disk image system. But I often use LVM2 volume for QEMU virtual machines and tried to take disk snapshot by virsh command ( snapshot-create DOMNAME --disk-only). So, finally qemu monitor command 'snapshot_blkdev' accepts the LVM2 volume and create QCOW2 snapshot image. In addition, domain's configuration file is replaced to use snapshot disk image instead of LVM2 volume. configuration file from .... <disk type='block' device='disk> <driver name='qemu' type='raw' cache='none'/> <source dev='dev/VG1/LVM2_dom'/> .... to <disk type='block' device='disk> <driver name='qemu' type='qcow2' cache='none'/> <source dev='dev/VG1/LVM2_dom.1317357844'/> After then, the domain runs well till it is shutdowned. I started the domain, but it does not with following error virtsh # start LVM2_dom error: Failed to start domain LVM2_dom error: 内部エラー Process exited while reading console log output: char device redirected to /dev/pts/7 qemu: could not open disk image /dev/VG1/LVM2_dom.1317357844: Invalid argument. I think that if the volume but qcow2 is given libvirt should be refuse, e.g. in qemuDomainSnapshotCreateDiskActive() with voulme driver type. But currently the structures concerning with snapshot or disk has no member to hold such a volume driver information. In addition, as we want to add the LVM2 and other volume snapshot function, we hope you add its information and fix. Regards MATSUDA Daiki

[libvirt] [PATCH V5 0/4] Support for multiple IP addresses using lists
by Stefan Berger 19 Nov '11

19 Nov '11

This patch series builds on the previously posted patch series https://www.redhat.com/archives/libvir-list/2011-October/msg00912.html and introduces the capability to assign a list to a variable and have multiple rules instantiated, one for each item in the list. This means, that if for example a variable like IP has been assigned a list of values IP = [1.2.3.4, 5.6.7.8, 10.0.0.1] it will instantiate 3 rules, which in turn allows us to build filters that can evaluate multiple possible values per field, i.e., allow the filtering for multiple IP addresses (per interface). v5: - addressing Eric Blake's comments v4: - addressing Daniel Berrange's comments - changed (default) behavior of iterator v3: - following Daniel Berrange's comment regarding how a list of items should be represented in the XML v2: - reimplementation of iterator - other nits Regards, Stefan

[libvirt] [PATCH V4 00/10] Make inner workings of nwfilters more flexible + extensions
by Stefan Berger 18 Nov '11

18 Nov '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. v4: - assign priority to chain according to name prefix - change default (internal) priorities of chains (by +200) - fix memory leak Regards, Stefan
