[libvirt] Support for Hyper-V
by Hassan Shaik 15 Feb '13

15 Feb '13

Hi, I would like to know if libvirt support Hyper-V deployed in Windows 2012 server. Does libvirt talk to Hyper-V using the REST API provided by Microsoft (where SCVMM & SPF are deployed)? Many thanks in advance. Regards, Hassan

[libvirt] [PATCH] [nwfilter] Fix libvirt upgrade path when nwfilter is used
by Stefan Berger 15 Feb '13

15 Feb '13

Between revision 65fb9d49 and before this patch, an upgrade of libvirt while VMs are running and instantiating iptables filtering rules due to nwfilter rules, may leave stray iptables rules behind when shutting VMs down. Left-over iptables rules may look like this: Chain FP-vnet0 (1 references) target prot opt source destination DROP tcp -- 0.0.0.0/0 0.0.0.0/0 tcp spt:122 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 [...] Chain libvirt-out (1 references) target prot opt source destination FO-vnet0 all -- 0.0.0.0/0 0.0.0.0/0 [goto] PHYSDEV match --physdev-out vnet0 The reason is that the recent nwfilter code only removed filtering rules in the libvirt-out chain that contain the --physdev-is-bridged parameter. Older rules didn't match and were not removed. Note that the user-defined chain FO-vnet0 could not be removed due to the reference from the rule in libvirt-out. Often the work around may be done through service iptables restart kill -SIGHUP $(pidof libvirtd) This patch now also removes older libvirt versions' iptables rules.

[libvirt] Boot VM with HLFS driver for Libvirt network disk (Online storage management)
by harryxiyou 14 Feb '13

14 Feb '13

Hi all, We have developed Online storage driver and Offline storage driver for Libvirt, which are located here. Online one: http://cloudxy.googlecode.com/svn/branches/hlfs/person/harry/hlfs/patches/h… Offline one: http://cloudxy.googlecode.com/svn/branches/hlfs/person/harry/hlfs/patches/h… HLFS(HDFS-based Log-structured FileSystem) has two modes, which are local mode and HDFS mode. We have tested HLFS driver for Libvirt with local way succesfully. However, when we test HDFS mode with HLFS driver for Libvirt network disk(Online storage Management), which needs "CLASSPATH" environment varaible, we must modify Libvirt source codes like following to set "CLASSPATH" environment variable. First location: Modify qemuBuildCommandLine func in src/qemu/qemu_command.c [...] 5731 if (deviceFlagMasked) 5732 qemuCapsSet(caps, QEMU_CAPS_DEVICE); 5733 if (!optstr) 5734 goto error; 5735 virCommandAddArg(cmd, optstr); 5736 VIR_FREE(optstr); 5737 /*TODO: submit this to Libvirt community, add this line!!!*/ 5738 virCommandAddEnvPass(cmd, "CLASSPATH"); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 5739 5740 if (!emitBootindex) 5741 bootindex = 0; 5742 else if (disk->info.bootIndex) 5743 bootindex = disk->info.bootIndex; [...] Second location: Modify virNetSocketForkDaemon func in /src/rpc/virnetsocket.c [...] 118 static int virNetSocketForkDaemon(const char *binary) 119 { 120 int ret; 121 virCommandPtr cmd = virCommandNewArgList(binary, 122 "--timeout=30", 123 NULL); 124 125 virCommandAddEnvPassCommon(cmd); 126 virCommandAddEnvPass(cmd, "XDG_CACHE_HOME"); 127 virCommandAddEnvPass(cmd, "XDG_CONFIG_HOME"); 128 virCommandAddEnvPass(cmd, "XDG_RUNTIME_DIR"); 129 /*TODO: submit this to libvirt community, add this line!!!!*/ 130 virCommandAddEnvPass(cmd, "CLASSPATH"); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 131 virCommandClearCaps(cmd); 132 virCommandDaemonize(cmd); 133 ret = virCommandRun(cmd, NULL); 134 virCommandFree(cmd); 135 return ret; 136 } [...] I boot VM with HLFS volume like following two ways. First way: Only execute "virsh create hlfs_hdfs.xml" ---------------------------------------------------------------------------- This way fails and i find this way just calls func virNetSocketForkDaemon but qemuBuildCommandLine func. Second way: first start "libvirtd" daemon, then execute "virsh create hlfs_hdfs.xml" ----------------------------------------------------------------------------------------------------------------------- This way works well. It calls qemuBuildCommandLine func, which need not call func virNetSocketForkDaemon. NOTE: hlfs_hdfs.xml is like this. $ cat hlfs_hdfs.xml <domain type='qemu'> <name>testvm</name> <memory>1048576</memory> <os> <type arch='x86_64'>hvm</type> </os> <devices> <disk type='network'> <source protocol="hlfs" name="hdfs:///tmp/testenv/testfs"/> <target dev='hda' bus='ide'/> </disk> <graphics type='vnc' port='-1' autoport='yes'/> </devices> </domain> I have some questions about up stuffs. 1, I wonder why first way (Only execute "virsh create hlfs_hdfs.xml") do not call qemuBuildCommandLine func, which may lead to fail to start VM with HLFS volume, right? 2, Maybe i have some understanding mistakes. You may also give other perfect ways to solve my prolems. After first way (Only execute "virsh create hlfs_hdfs.xml"), i get following logs(ALL). $ ./virsh create hlfs_hdfs.xml 2013-02-14 03:32:04.311+0000: 23205: info : libvirt version: 1.0.1 2013-02-14

[libvirt] [PATCHv2 0/5] S390: Support for native CCW bus
by Viktor Mihajlovski 14 Feb '13

14 Feb '13

Originally, QEMU did not implement a native I/O bus for s390. The initial implementation had a machine type 's390-virtio' featuring a fully paravirtualized I/O system with an artificial bus type 'virtio-s390'. This bus had a number of short-comings, like the need for a non-standard device discovery mechanism, a limited number of devices, limited hotplugging capabilites and the lack of persistent device addresses. To resolve these issues a new machine type 's390-ccw-virtio' has been recently added to QEMU which implementa the native s390 CCW I/O bus. Guests with arch='s390x' and machine='s390-ccw-virtio' can now be defined with up to 262144 virtio devices. This series adds the support for the s390-ccw-virtio machine type and the CCW bus to libvirt. As usual we start with the documentation/schema, the generic configuration stuff, continue with the QEMU driver including device hotplug and finally add qemu2xml testcases. V2 Changes - use an attribute triple cssid, ssid, schid instead of devno to better represent the libvirt CCW address structure - rebase to current upstream, mainly address qemuCapsXXX rename J.B.

[libvirt] Thoughts on adding a domain type of jvm
by Scott Stark 13 Feb '13

13 Feb '13

I'm working with a java vm vendor that is developing a multi-tenancy jvm and is trying to leverage the libvirt framework for the domain configuration. Right now the java language binding leverages the libvirt c library for parsing the domain.xml file. What are the thoughts on adding a 'jvm' domain type? I believe there would need to be a jvm specific section in a separate namespace similar to the qemucmdline section.

[libvirt] Host information from libvirt KVM/Xen
by Parakkal, Navin S 13 Feb '13

13 Feb '13

Hi, I'm able to get the CPU utilization metrics from libvirt for the guests (VM's) remotely . Is it possible to get the Host Cpu stat's through libvirt ? I didn't find any information regarding the host cpu cycles and memory utilization to collect them remotely. Libvirt is installed on all the hosts. Regards, Navin
