[libvirt] [PATCH 0/3] Make UEFI firmware config simpler

This series lets apps enabled UEFI for a guest by simply doing <loader firmware='uefi'/> with the other (existing) attributes being auto-filled with correct QEMU specific defaults. Daniel P.

[libvirt] [PATCH v2 0/2] New libssh transport
by Pino Toscano 19 Oct '16

19 Oct '16

Hi, this series introduces a new libssh transport in libvirt, based on the libssh C library. This library supports what libssh2 does, and more: - easier API for known_hosts handling (there's a ticket upstream to request extensions for it, but what is implemented now works well) - potential GSSAPI authentication (not enabled yet because of a libssh bug [1]) - easier API for ssh-agent support The implementation for the new transport is based on the libssh2 one, hence it shares origin and style. [1] https://red.libssh.org/issues/242 Thanks, Changes from v1 to v2: - implemented keyboard interactive - code polish, and fixes Pino Toscano (2): virNetSocket: allow to not close FD libssh_transport: add new libssh-based transport config-post.h | 2 + configure.ac | 3 + include/libvirt/virterror.h | 2 + m4/virt-libssh.m4 | 26 + src/Makefile.am | 21 +- src/libvirt_libssh.syms | 22 + src/remote/remote_driver.c | 41 ++ src/rpc/virnetclient.c | 123 ++++ src/rpc/virnetclient.h | 13 + src/rpc/virnetlibsshsession.c | 1424 +++++++++++++++++++++++++++++++++++++++++ src/rpc/virnetlibsshsession.h | 80 +++ src/rpc/virnetsocket.c | 184 +++++- src/rpc/virnetsocket.h | 13 + src/util/virerror.c | 9 +- 14 files changed, 1959 insertions(+), 4 deletions(-) create mode 100644 m4/virt-libssh.m4 create mode 100644 src/libvirt_libssh.syms create mode 100644 src/rpc/virnetlibsshsession.c create mode 100644 src/rpc/virnetlibsshsession.h -- 2.7.4

[libvirt] [RFC] make virDomainQemuMonitorCommand work in any libvirt state
by Nikolay Shirokovskiy 19 Oct '16

19 Oct '16

Hi, all. We would like to use virDomainQemuMonitorCommand to query qemu independently of libvirt state. Currenly it is not possible. This API call takes job condition just like any other call and thus is unavailable on any lengthy(or stucked) synchronous job. I've already posted this question in list, just failed to find the reference. Somebody suggested to use proxy (and even an implementation) in between qemu and libvirt that can inject commands to qemu and filter replies. It is not really convinient. This way test setups will be different from production and we can not investigate problems in production environment. I'd like to drop acquiring job condition in the call as this function does not deal with libvirt state (except for the taint but is is ok, we will not mess things up here). But this is not enough, we need to make qemu monitor deal with many qemu commands simultaneously. Looks like it is quite a big change for test/debug case. But I guess eventually normal user cases can get benefits too from this monitor changes. For example all query API calls that query qemu directly can be changed to not to wait for some synchronous job finishing.(qemuDomainGetBlockJobInfo for example). Nikolay

[libvirt] How libvirt address qemu command line args
by zhunxun＠gmail.com 19 Oct '16

19 Oct '16

Now I want to add some args about TPM to domain's XML,so I can start a domain by virt-manager or other virsh command,and then ,I would like to use sVIrt security context to label vTPM and correspondingVM,But I do not know how to get these XML args in libvirt. the key problem is that how can i get and recognize these args!!! related XML content : <qemu:commandline> <qemu:arg value='-enable-kvm'/> <qemu:arg value='-drive'/> <qemu:arg value='file=/root/nvram_2.0-jin.qcow2,if=none,id=nvram0-0-0,format=qcow2'/> <qemu:arg value='-device'/> <qemu:arg value='tpm-tis,tpmdev=tpm-tpm0,id=tpm0'/> <qemu:arg value='-tpmdev'/> <qemu:arg value='libtpms,id=tpm-tpm0,nvram=nvram0-0-0,startup=clear'/> <qemu:arg value='-bios'/> <qemu:arg value='/root/xenSeabios/out/bios.bin'/> </qemu:commandline> zhunxun(a)gmail.com
