[libvirt] serial console/events example script

by Dave Allan

Hi all, A while back I wrote the attached code to demonstrate how to use events and serial console to create a serial console that stays up even when the VM is down. Is it worth adding to the examples? It might need some work, as I am not terribly strong with Python. Dave

[libvirt] [PATCH 0/3 v4] use qemu's dump-guest-meory when vm uses host device

by Wen Congyang

Currently, we use migrate to dump guest's memory. There is one restriction in migrate command: the device's status should be stored in qemu because the device's status should be passed to target machine. If we passthrough a host device to guest, the device's status is stored in the real device. So migrate command will fail. We usually use dump when guest is panicked. So there is no need to store device's status in the vmcore. qemu will have a new monitor command dump-guest-memory to dump guest memory, but it doesn't support async now(it will support later when the common async API is implemented). So I use dump-guest-memory only when the guest uses host device in this patchset. Note: the patchset for qemu is still queued. Luiz has acked, but he said he does not wait an ACK from Jan and/or Anthony. Changes from v3 to v4: 1. allow the user to specify the core file's format Changes from v2 to v3: 1. qemu supports the fd that is associated with a pipe, socket, or FIFO. So pass a pipe fd to qemu and O_DIRECT can work now. Change from v1 to v2: 1. remove the implemention for text mode.

[libvirt] [PATCH v2] [TCK] nwfilter: Add test cases for ipset

by Stefan Berger

Add test cases for ipset support. Since ipset may not be available on all system, the first line of the XML file containing the test filter has been extended with a specially formatted XML comment containing a command line test for whether the test case can be run at all. The format of that line is:  If the tests in this line don't succeed, the test case is skipped. Also add a test case cleaning up the created ipset. Run this test after all other tests using alphabetical ordering. --- v2: - addressed Eric Blake's comments --- scripts/nwfilter/nwfilter2vmtest.sh | 36 +++++++-- scripts/nwfilter/nwfilterxml2fwallout/ipset-test.fwall | 39 ++++++++++ scripts/nwfilter/nwfilterxml2fwallout/zzz-ipset-cleanup.fwall | 1 scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml | 25 ++++++ scripts/nwfilter/nwfilterxml2xmlin/zzz-ipset-cleanup.xml | 5 + 5 files changed, 99 insertions(+), 7 deletions(-) Index: libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml =================================================================== --- /dev/null +++ libvirt-tck/scripts/nwfilter/nwfilterxml2xmlin/ipset-test.xml @@ -0,0 +1,25 @@ + +<filter name='tck-testcase' chain='root'> + <uuid>5c6d49af-b071-6127-b4ec-6f8ed4b55335</uuid> + <rule action='accept' direction='out'> + <all ipset='tck_test' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='in'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='in+NONE'/> + </rule> + <rule action='accept' direction='out'> + <all state='NONE' ipset='tck_test' ipsetflags='src,dst' comment='out+NONE'/> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,DST,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='tck_test' ipsetflags='SRC,dSt,SRC' /> + </rule> + <rule action='accept' direction='in'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' /> + </rule> + <rule action='accept' direction='inout'> + <all ipset='$IPSETNAME' ipsetflags='src,dst' comment='inout'/> + </rule> +</filter> Index: libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh =================================================================== --- libvirt-tck.orig/scripts/nwfilter/nwfilter2vmtest.sh +++ libvirt-tck/scripts/nwfilter/nwfilter2vmtest.sh @@ -107,6 +107,7 @@ checkExpectedOutput() { ifname="$3" flags="$4" skipregex="$5" + skiptest="$6" regex="s/${ORIG_IFNAME}/${ifname}/g" tmpdir=$(mktmpdir) @@ -147,6 +148,18 @@ checkExpectedOutput() { break fi + if [ -n "${skiptest}" ]; then + # treat all skips as passes + passctr=$(($passctr + 1)) + [ $(($flags & $FLAG_VERBOSE)) -ne 0 ] && \ + echo "SKIP ${xmlfile} : ${cmd}" + [ $(($flags & $FLAG_LIBVIRT_TEST)) -ne 0 ] && \ + test_result $(($passctr + $failctr)) "" 0 + [ $(($flags & $FLAG_TAP_TEST)) -ne 0 ] && \ + tap_pass $(($passctr + $failctr)) "SKIP: ${xmlfile} : ${skiptest}" + break + fi + diff -w ${tmpfile} ${tmpfile2} >/dev/null if [ $?

[libvirt] [PATCH] storage backend: Add RBD (RADOS Block Device) support

by Wido den Hollander

This patch adds support for a new storage backend with RBD support. RBD is the RADOS Block Device and is part of the Ceph distributed storage system. It comes in two flavours: Qemu-RBD and Kernel RBD, this storage backend only supports Qemu-RBD, thus limiting the use of this storage driver to Qemu only. To function this backend relies on librbd and librados being present on the local system. The backend also supports Cephx authentication for safe authentication with the Ceph cluster. For storing credentials it uses the build-in secret mechanism of libvirt.

[libvirt] [PATCH 0/6] support to set cpu bandwidth for hypervisor threads

by Wen Congyang

Currently, we only can set cpu bandwidth for vcpu. If the hypervisor threads consume too much cpu time, it may affect the vcpu. This patchset allows the user to control the cpu bandwidth for hypervisor threads. It does not change the behavior if the cpu bandwidth for hypervisor is unlimited.

[libvirt] [PATCH 0/2] qemu: Add support for -no-user-config

by Jiri Denemark

Eduardo submitted patches[1] for qemu implementing -no-user-config as a better alternative to all-or-nothing -nodefconfig. With this new option, we are finally able to use modern CPU models defined in qemu's configuration file without allowing user-supplied qemu configuration to mess up with qemu processes started by libvirt. The qemu patches are not committed upstream yet (and this patchset won't be committed either until qemu support is finished) but they are very close and are expected to make it into qemu-1.1.

[libvirt] [PATCH] openvz: read vmguarpages/privvmpages to set memory tunables [v2]

by Guido Günther

--- This is a reworked version of the patch already sent, now adding handling for "unlimited" (represented by LONG_MAX in openvz) as well as a schema testcase. I also switched all value to unsigned long long to avoid overflows. Note that privvmpages is the amount of memory available to the application. The total memory usage of the container might be higher due to used kernel memory. This does probably warrant an extra tunable later. O.k. to apply?

[libvirt] [PATCH V3] nwfilter: Add support for ipset

by Stefan Berger

This patch adds support for the recent ipset iptables extension to libvirt's nwfilter subsystem. Ipset allows to maintain 'sets' of IP addresses, ports and other packet parameters and allows for faster lookup (in the order of O(1) vs. O(n)) and rule evaluation to achieve higher throughput than what can be achieved with individual iptables rules. On the command line iptables supports ipset using iptables ... -m set --match-set <ipset name> <flags> -j ... where 'ipset name' is the name of a previously created ipset and flags is a comma-separated list of up to 6 flags. Flags use 'src' and 'dst' for selecting IP addresses, ports etc. from the source or destination part of a packet. So a concrete example may look like this: iptables -A INPUT -m set --match-set test src,src -j ACCEPT Since ipset management is quite complex, the idea was to leave ipset management outside of libvirt but still allow users to reference an ipset. The user would have to make sure the ipset is available once the VM is started so that the iptables rule(s) referencing the ipset can be created. Using XML to describe an ipset in an nwfilter rule would then look as follows: <rule action='accept' direction='in'> <all ipset='test' ipsetflags='src,src'/> </rule> The two parameters on the command line are also the two distinct XML attributes 'ipset' and 'ipsetflags'. FYI: Here is the man page for ipset: https://ipset.netfilter.org/ipset.man.html Regards, Stefan --- v3: - use DATATYPE_IPSETNAME for the name of the ipset - adapted documentation for 0.9.12 v2: - split ipset description into ipset and ipsetflags attribute - improved on documentation --- docs/formatnwfilter.html.in | 64 ++++++++++++++ docs/schemas/nwfilter.rng | 23 +++++ src/conf/nwfilter_conf.c | 136 +++++++++++++++++++++++++++++- src/conf/nwfilter_conf.h | 13 ++ src/nwfilter/nwfilter_ebiptables_driver.c | 75 +++++++++++++++- tests/nwfilterxml2xmlin/ipset-test.xml | 24 +++++ tests/nwfilterxml2xmlout/ipset-test.xml | 24 +++++ tests/nwfilterxml2xmltest.c | 2 8 files changed, 356 insertions(+), 5 deletions(-) Index: libvirt-acl/src/conf/nwfilter_conf.c =================================================================== --- libvirt-acl.orig/src/conf/nwfilter_conf.c +++ libvirt-acl/src/conf/nwfilter_conf.c @@ -183,6 +183,8 @@ static const char dstportstart_str[] = " static const char dstportend_str[] = "dstportend";
