[libvirt] [PATCH v2] bhyve: add console support through nmdm device
by Roman Bogorodskiy 23 Mar '14

23 Mar '14

Changes from v1: Switch over from implicit slave device path, i.e. guessing from <source path='/dev/nmdm0A'/> that the slave is '/dev/nmdm0B', to explicit master and slave device specification using <source master='/dev/nmdm0A' slave='/dev/nmdm0B'/>.

[libvirt] [PATCH v8 0/4] support dumping guest memory in compressed format
by qiaonuohan＠cn.fujitsu.com 23 Mar '14

23 Mar '14

dumping guest's memory is introduced without compression supported, but now qemu can dump guest's memory in kdump-compressed format. This patchset is used to add support in libvirt side to let qemu do the dump in compressed format and please refer the following address to see implementation of the qemu side, the lastest version of qemu side is v9. http://lists.nongnu.org/archive/html/qemu-devel/2014-02/msg03016.html ChangLog: Changes from v7 to v8: 1. add test for qemuMonitorGetDumpGuestMemoryCapability 2. fix a bug when dumping a elf core with the an older version of qemu Changes from v6 to v7: 1. revert changing dumpformat of virDomainCoreDumpWithFormat back to an enum Changes from v5 to v6: 1. add qemuMonitorGetDumpGuestMemoryCapability API to check the available dump format Changes from v4 to v5: 1. modify some restriction check Changes from v3 to v4: 1. dropping patch "add dump_memory_format in qemu.conf" 2. fix to follow some conventions Changes from v2 to v3: 1. address Jiri Denemark's comment about adding a new public API instead of changing an old one. Changes from v1 to v2: 1. address Daniel P. Berrange's comment about using a new parameter to replace flags like VIR_DUMP_COMPRESS_ZLIB. qiaonuohan (4): add new virDomainCoreDumpWithFormat API qemu: add qemuMonitorGetDumpGuestMemoryCapability qemu: add support for virDomainCoreDumpWithFormat API allow "virsh dump --memory-only" specify dump format include/libvirt/libvirt.h.in | 31 ++++++++++++++ src/driver.h | 7 ++++ src/libvirt.c | 98 ++++++++++++++++++++++++++++++++++++++++++++ src/libvirt_public.syms | 5 +++ src/qemu/qemu_driver.c | 75 ++++++++++++++++++++++++++++----- src/qemu/qemu_monitor.c | 27 ++++++++++-- src/qemu/qemu_monitor.h | 6 ++- src/qemu/qemu_monitor_json.c | 85 +++++++++++++++++++++++++++++++++++--- src/qemu/qemu_monitor_json.h | 6 ++- src/remote/remote_driver.c | 1 + src/remote/remote_protocol.x | 15 ++++++- src/remote_protocol-structs | 7 ++++ src/test/test_driver.c | 22 ++++++++-- tests/qemumonitorjsontest.c | 45 +++++++++++++++++++- tools/virsh-domain.c | 47 +++++++++++++++++++-- tools/virsh.pod | 6 +++ 16 files changed, 454 insertions(+), 29 deletions(-) -- 1.8.5.3

[libvirt] RFE: Make saveDir/cacheDir/snapshotDir/dumpDir configurable and allow per-domain paths
by Till Maas 21 Mar '14

21 Mar '14

Hi, I would like to separate all data of libvirt domains so that each domain can easily be deleted securely. However libvirt by default uses static directories to store data from domains such as snapshots, current states and dumps. Also a cache dir is used for reasons unknown to me. To separate the data, I would like to use different directories for each domain. For this these paths need to be configurable e.g. in qemu.conf and it needs to be possible to for example specify a placeholder in the path that is substituted by the domain's name, so that e.g.: /srv/{name}/save/ can be specified to use /srv/dom1/save/dom1.save as save path. This change should have low impact on regular users, because the defaults can be set to match the current behaviour. What is your opinion on this? Do you have any ideas about how to do the name substitution best? Kind regards Till P.S.: I am not subscribed to the list so please CC me.

[libvirt] More java bindings functions
by Pasquale Dir 21 Mar '14

21 Mar '14

Hello, I just added, because I needed them, two new bindings for java apis: Connection.getCpuStats(int, long) and Domain.getCpuStats(int, long) these two functions act like python's counterpart. I give you the .jar with sources so that, after you review it (it works but I am not entirely sure it is bug free), you could publish it thus helping java programmers who needed a cpu indicator too. Regards, Pasquale Di Rienzo

[libvirt] [PATCH][RFC] Add a rule for indenting labels
by Ján Tomko 21 Mar '14

21 Mar '14

Indent labels by one space. Add the rule to HACKING and enforce it by syntax-check. --- Adding a space helps git's function context detection, but the fallout patch is over 800K. My reasoning for also indenting labels in nested code is that vim's cinoptions don't have a separate option for these labels (or I haven't searched hard enough?).
