[libvirt] Sharing file between host and guest
by Yushu Yao 12 Sep '08

12 Sep '08

Hi All, Question not very related to libvirt but I think most of the real VM experts are in this list. What is the best and fastest way to share files between guest and host? Something like the share folders-hgfs in vmware might work, but is there a way that works on all hypervisors? Network based file sharing (NFS/Samba) are limited by the speed of the virtual network interfaces. Maybe one can do it through USB? Thanks a lot! -yushu

[libvirt] [PATCH] make consistent assumptions about libvirtd dependence
by David Lively 12 Sep '08

12 Sep '08

Hi - Currently src/Makefile.am says that only the QEMU, LXC, and storage drivers are dependent on libvirtd. But the driver registration code in virInitialize wasn't registering the remote or openVz driver when WITH_LIBVIRTD was not defined. The attached patch makes the virInitialize code consistent with the assumptions stated in src/Makefile.am. But note I'm assuming the assumptions in src/Makefile.am are correct. I'm not sure what's really dependent on libvirtd, so Someone Who Knows Better should verify this. Thanks, Dave commit 24d5708877fce90c4e85e3b2ede07b74f4a98224 Author: David Lively <dlively(a)virtualiron.com> Date: Thu Sep 11 11:56:20 2008 -0400 Make driver registration assume the same libvirtd dependences expressed in src/Makefile.am (i.e., that only the QEMU, LXC, and storage drivers depend on libvirtd). diff --git a/src/libvirt.c b/src/libvirt.c index 54ed8cf..3d66f5a 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -286,20 +286,20 @@ virInitialize(void) #ifdef WITH_XEN if (xenUnifiedRegister () == -1) return -1; #endif -#ifdef WITH_LIBVIRTD -#ifdef WITH_QEMU - if (qemudRegister() == -1) return -1; +#ifdef WITH_REMOTE + if (remoteRegister () == -1) return -1; #endif #ifdef WITH_OPENVZ if (openvzRegister() == -1) return -1; #endif +#ifdef WITH_LIBVIRTD +#ifdef WITH_QEMU + if (qemudRegister() == -1) return -1; +#endif #ifdef WITH_LXC if (lxcRegister() == -1) return -1; #endif if (storageRegister() == -1) return -1; -#ifdef WITH_REMOTE - if (remoteRegister () == -1) return -1; -#endif #endif return(0);

[libvirt] PATCH: Latest MinGW patches
by Daniel P. Berrange 12 Sep '08

12 Sep '08

I've got a MinGW build environment setup on Fedora 10 now, so just checked out what the latest state of libvirt CVS is. With the attached patch, I can run configure with: ./configure \ --build=i686-pc-linux-gnu \ --host=i686-pc-mingw32 \ --prefix=/usr/i686-pc-mingw32/sys-root/mingw \ --without-libvirtd \ --without-xen \ --without-qemu \ --without-sasl \ --without-lxc \ --without-openvz \ --without-python So, basically only the 'test' and 'remote' drivers are turned on. And do a build which produces a libvirt-0.dll and a virsh.exe which is I can run under Wine successfully. The changes: - The src/Makefile.am was conditionally turning off individual storage driver backends, based on the WITH_LIBVIRTD conditional. THis gave confusing diagnositics, since the configure summary said they were turned on. So, now configure itself turns off the storage drivers if libvirtd is disabled. - The storage_backend.c file is used by storage_Conf.c, so we need to compile this even if all storage backends are disabled. So we tweak src/Makefile.am to achieve this, and add a few more bits of conditional logic inside storage_backend.c to cope with the base directory pool driver not being available. - Mingw is missing regex.h and sys/wait.h, which are used in the generic storage_backend.c file. We check for those in configure and conditionalize their inclusion. Furthermore we disable the virStorageBackendRunProgRegex and virStorageBackendRunProgNul functions on Windows, since they're not required and not compilable without regex.h / sys/wait.h - Mingw is mising getuid() and getgid() which are used in the storage_conf XML parser. We check for and optionally disable them and initialize uid/gid to 0 if missing. - The virExec() stub routine for Mingw didn't have its signature updated when i did the recent virExe changes.

[libvirt] [RFC][PATCH] virt-manager calls migration API
by S.Sakamoto 11 Sep '08

11 Sep '08

Hi, I just make the proto patch that calls migration API from virt-manager. Form unity point of view, This proto patch adds Migrate in as same layer as operations for the Domain. Fisrt, this patch adds "Migrate" to the right-click menu when selected a domain. Run Run Pause Pause Shutdown Shutdown --------- ---> -------- Open(O) Migrate -------- Open(O) When "Migrate" selected, it goes on new window open which shows available(have been connecting) hosts. Of course, I have been knowing that there is Drag&Drop way. By the way, (1)It is necessary to migrate a domain that users modify an environmental setting. (ex. for XenD xend-config, ...) And (2)I think it that is necessary to improve usability that there is "precheking" beofre migrating. (ex. same cpu family/processor number?, enough free memory?, ...) Do you already have a idea that virt-manager servies above (1)(2) ? Finally, I understand that migrated domain's state switches Running and Shutoff alternately, because current virt-maneger manages domains by UUID. Is there a plan that this problem is solved? virtManager/domain.py | 27 ++++++ virtManager/engine.py | 82 ++++++++++++++++++++ virtManager/hostlist.py | 172 ++++++++++++++++++++++++++++++++++++++++++ virtManager/manager.py | 27 ++!!!! vmm-hostlist.glade | 195 ++++++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 488 insertions(+), 15 modifications(!) Thanks, Shigeki Sakamoto.

[libvirt] <soapbox>Thoughts on Open Source Hypervisor management
by Nathan Charles 09 Sep '08

09 Sep '08

Over the the last few years I've setup and experimented with a large number of vm technologies. Everything from x86 based stuff like VMware, kvm, qemu, xen, to more exotic things like hercules, and z/VM. So far the solution I've found to be the most baked is VMware ESX with Virtual Center. It's pretty sweet to set up a DRS cluster and have VM's load balance across available hardware. However, It's super expensive and is in bed with windows way to much. i.e. Virtual Center and the Virtual Infrastructure Client only run on windows don't have LDAP auth and only use MSQL. I've also been working implementing a provisioning solution for our developers. We do automated installation of hundreds of machines of which many are underutilized. Many are newer machines with some pretty beefy specs (8 cores and at least 8 gigs of ram). I've done a lot of thinking in a vacuum about what would be ideal. There's a lot out there I don't know so I hope you give me some grace as I talk. So I want to be able to pull these machines into a cluster of hypervisors; a VM fabric aggregated via software. Or thought of in another way a p2p vm cluster. In some ways I think oVirt is the closest and in someways I think simply extending libvirt would be better and sometimes I think it should be a new project. So I thought I'd post this and see what people think. Since I'm still unsure as to where the proper place to abstract this is, I'll use the working package name of genet for the rest of the discussion. >From my perspective the reason I can't use most of the open source virtualization solutions for more than local vm's is one of management. They're great for one machine but as soon as you get to more than one machine there is a lot of human administrative overhead. oVirt seems like it could be really good, but in an existing environment it requires a lot of substantial changes and requires significant modification to work with an existing provisioning infrastructure. So as I imagined a silver bullet I used biology as a metaphor and used started thinking with the idea of "every piece contains the image of the whole." So the here's the 10,000 ft overview of an idea. 1. cluster administration is done from the command line 2. cluster administration can be performed from any node. 3. a new node can join a cluster on a local subnet with one command. 4. local storage resources are presented to the cluster so there is no need to have predefined NAS/SAN/iSCSI 5. cluster will load balance vm instances from node to node. 6. a node shouldn't need more than one nic but adding additional nic's provides failover and load balancing. I'm kind of ignoring storage at this point, but I think it's the biggest pieces of the puzzle as long as migration needs network/san storage. The ideal scenario would be something really simple like if I have SAN connectivity use that else I use some sort of cluster file system which adds in local storage and doesn't require reformating, but that might be wistful thinking. Use cases 1. looking for clusters on the same subnet via avahi # [yum|apt-get] install genet # genet list clusters forsythia hazelnut sumac # rhizome info sumac Password: sumac info: 8 nodes 64 Cores 128 G Ram 1.5 T storage 50% Cluster CPU utilized 75% Memory utilized 80% Storage utilized 2. a machine joins an existing cluster # genet join sumac Password: localhost has successfully joined sumac # Help output #genet -h usage: genet [options] command genet is a simple command line interface for creating and maintaining a cluster of hypervisors. Commands: create cluster [cluster name] create vm [vm name] (probably integrates with virt-install) evacuate [hostname] - migrate all vm instances off of [hostname] (defaults to localhost) list clusters [hostname] - list clusters on local subnet or via hostname on another network/subnet list vm [cluster] - list all vm instances in a cluster defaults to cluster local node is in. console [vmname] - virt-viewer to vmname So this all begs the the statement, "show me the code" and I think that perfectly valid. I may write some code, but I don't want to duplicate effort and I want to find out what other people are thinking. I welcome your thoughts. </soapbox> Regards, -- Nathan Charles
