[libvirt] [test-API PATCH 0/5] add TESTCASE_check optional function support
by Guannan Ren 16 Apr '12

16 Apr '12

In some cases, we need to check if the testing environment is satisfied to run a certain testcase. The testcase only will be executed If some specific hardware is present on box. The patches add a optional check function support. For example: a testcase named testa.py with testa_check() defined in this file. The framework will run test_check(params) first, return 0 means pass, 1 means failure. If the check function failed. the testa(params) will not be run. "Skip" is marked in output. # testa.py required_params = () optional_params = ('options') def testa_check(params): logger = params['logger'] logger.info("I am from testa_check") return 1 def testa(params): logger = params['logger'] logger.info("I am from testa") return 1 The Output: Checking Testing Environment...

[libvirt] [PATCH V9 0/6] Add DHCP snooping support to nwfilter
by Stefan Berger 14 Apr '12

14 Apr '12

This series of patches adds DHCP snooping support to libvirt's nwfilter subsystem. DHCP snooping detects DHCP leases obtained by a VM and automatically adjusts the network traffic filters to reflect the IP addresses with which a VM may send its traffic, thus for example preventing IP address spoofing. Once leases on IP addresses expire or if a VM gives up on a lease on an IP address, the filters are also adjusted. All leases are persisted and automatically applied upon a VM's restart. Leases are associated with the tuple of VM-UUID and interface MAC address. The following interface XML activates and uses the DHCP snooping: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='ip_learning' value='dhcp'/> </filterref> </interface> Regards, David and Stefan

[libvirt] [PATCH] blockjob: add virsh blockjob --wait
by Eric Blake 13 Apr '12

13 Apr '12

I'm tired of shell-scripting to wait for completion of a block pull, when virsh can be taught to do the same. I couldn't quite reuse vshWatchJob, as this is not a case of a long-running command where a second thread must be used to probe job status (at least, not unless I make virsh start doing blocking waits for an event to fire), but it served as inspiration for my simpler single-threaded loop. There is up to a half-second delay between sending SIGINT and the job being aborted, but I didn't think it worth the complexity of a second thread and use of poll() just to minimize that delay. * tools/virsh.c (cmdBlockPull): Add new options to wait for completion.

[libvirt] ANNOUNCE: Release of libvirt-sandbox version 0.0.3
by Daniel P. Berrange 13 Apr '12

13 Apr '12

I pleased to announce the a new public release of libvirt-sandbox, version 0.0.3, is now available for download ftp://libvirt.org/libvirt/sandbox/ The packages are GPG signed with Key fingerprint: DAF3 A6FD B26B 6291 2D0E 8E3F BE86 EBB4 1510 4FDF (4096R) The libvirt-sandbox package provides an API layer on top of libvirt-gobject which facilitates the cration of application sandboxes using virtualization technology. An application sandbox is a virtual machine or container that runs a single application binary, directly from the host OS filesystem. In other words there is no separate guest operating system install to build or manager. At this point in time libvirt-sandbox can create sandboxes using either LXC or KVM, and should in theory be extendable to any libvirt driver. The first release is able to run simple command line based programs. This release has focused on making the sandbox infrastructure more reliable and expanding the functionality available. Dan Walsh has also contributed a new tool called virt-sandbox-service which facilitates the creation of sandboxes for running system services like apache. - Ensure root/config filesystems are readonly in KVM - Add support for mounting host disk images in guests - Add support for binding guest filesystems to new locations - Add support for an optional interactive shell for debugging or administrative purposes - Add a virt-sandbox-service script for preparing sandboxes for system services, integrating with systemd - Misc compiler warning fixes - Replace invocation of insmod with direct syscalls - Refactor API to separate interactive sandbox functionality from base class & service sandbox functionality - Rewrite host/guest I/O handling to separate stdout from stderr correctly, improve reliability of startup/shutdown handshakes and propagate exit status back to host - Exec away the first hypervisor specific init process, so generic init process get PID 1 - Turn on reboot-on-panic in KVM to ensure guest exists on fatal problems Some examples $ virt-sandbox -c qemu:///session /bin/date Thu Jan 12 22:30:03 GMT 2012 $ virt-sandbox -c qemu:///session /bin/cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 2 model name : QEMU Virtual CPU version 1.0 stepping : 3 cpu MHz : 2793.084 cache size : 4096 KB fpu : yes fpu_exception : yes cpuid level : 4 wp : yes flags : fpu de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pse36 clflush mmx fxsr sse sse2 syscall nx lm up rep_good nopl +pni cx16 hypervisor lahf_lm bogomips : 5586.16 clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: $ virt-sandbox -c lxc:/// /bin/sh sh-4.2$ ps -axuwf USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND berrange 1 0.0 0.1 167680 4688 pts/0 S+ 22:31 0:00 libvirt-sandbox-init-common berrange 47 0.0 0.0 13852 1608 pts/1 Ss 22:31 0:00 \_ /bin/sh berrange 48 0.0 0.0 13124 996 pts/1 R+ 22:31 0:00 \_ ps -axuwf Feedback / patches / etc should be directed to the main libvirt development mailing list.
