[libvirt] [PATCH v3 0/9] Add basic driver for Parallels Virtuozzo Server
by Dmitry Guryanov 19 Apr '12

19 Apr '12

Parallels Virtuozzo Server is a cloud-ready virtualization solution that allows users to simultaneously run multiple virtual machines and containers on the same physical server. Current name of this product is Parallels Server Bare Metal and more information about it can be found here - http://www.parallels.com/products/server/baremetal/sp/. This driver will work with PVS version 6.0 , beta version scheduled at 2012 Q2.

[libvirt] [PATCH 0/3] tighten up integer parsing
by Eric Blake 19 Apr '12

19 Apr '12

I thought my recent improvements to <memory> parsing were complete, until I stumbled upon https://bugzilla.redhat.com/show_bug.cgi?id=617711, which shows a file that fails 'virt-xml-validate' but was silently accepted, and worse, misintepreted the user's intentions. I didn't have time to scrub the entire code base, but I can at least prevent the clean files from getting worse.

[libvirt] [PATCH 0/2 v2] use qemu's dump-guest-meory when vm uses host device
by Wen Congyang 19 Apr '12

19 Apr '12

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 waits an ACK from Jan and/or Anthony. They are too busy, and donot reply. Change from v1 to v2: 1. remove the implemention for text mode.

Hi, I looked deeper into these thread-safety issues, once a new connection is opened for each thread, everything works well. However, opening and closing connections isn't thread-safe at all for two reasons : - VirtualBox C bindings initialization and uninitialization functions aren't thread-safe. I talked about it with upstream on IRC and they are probably not going to fix it, but would accept a patch fixing the issue. I'm going to contact upstream again to get some advices so I can write a patch. - In the libvirt vbox driver, for each new connection, modification of the global variable g_pVBoxGlobalData isn't protected (see line 1040 of vbox_tmpl.c). First of all, is it really necessary to replace it on each new connection, or would it be ok to initialize it only when the first connection is opened ? A global mutex is needed in the vbox driver to protect access to g_pVBoxGlobalData, the vboxRegister() function seems to be the best place to initialize such a mutex unless there is another entry point to do this ? -- Jean-Baptiste ROUAULT Ingénieur R&D - diateam : Architectes de l'information Phone : +33 (0)2 98 050 050 Fax : +33 (0)2 98 050 051

[libvirt] [PATCH V12 0/5] Add DHCP snooping support to nwfilter
by Stefan Berger 19 Apr '12

19 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='CTRL_IP_LEARNING' value='dhcp'/> </filterref> </interface> Once an IP address has been detected on an interface, 'virsh dumpxml <vm>' would show the IP address lease in the format <IP address>,<lease timeout in seconds>: <interface type='bridge'> <source bridge='virbr0'/> <filterref filter='clean-traffic'> <parameter name='CTRL_IP_LEARNING' value='dhcp'/> <parameter name='IP_LEASE' value='192.168.122.210,180'/> </filterref> </interface> Regards, David and Stefan
