[libvirt] [PATCH] Wrong comments
by Anton Protopopov 17 Sep '08

17 Sep '08

Hi! In comments to structure 'virDomainInfo' there was reference to smth of type 'virDomainFlags'. Actually, the type of this field must be 'virDomainState'. Patch includes another one such replacement. There is another place where 'virDomainFlags' mentioned: src/xend_internal.c. I think, that argument must be of type 'virConnectFlags', but it is marked as ATTRIBUTE_UNUSED, so I leave the comment as it is :) And why are you writing unsigned char state; instead of virDomainState state; ?

[libvirt] [PATCH] spec file enhancements for minimal "client-only" build
by Ben Guthro 17 Sep '08

17 Sep '08

Attached is a patch to add some additional options to the spec file, allowing for more flexibility when building. With this patch, it allows you to build a "client-only" version of libvirt for machines that may have an interest in communicating over the remote driver, but do not have a hypervisor themselves. It enables command line overrides of control variables for the build eg: rpmbuild $(RPM_FLAGS) --nodeps \ --without xen \ --without xen_proxy \ --without qemu \ --without openvz \ --without lxc \ --without polkit \ --without libvirtd \ --without avahi \ --without sasl \ --without python \ --without devel \ -ta --clean libvirt*.tar.gz Signed-off-by: Ben Guthro <bguthro(a)virtualiron.com> diff --git a/libvirt.spec.in b/libvirt.spec.in index 18b2127..666fb83 100644 --- a/libvirt.spec.in +++ b/libvirt.spec.in @@ -1,11 +1,16 @@ # -*- rpm-spec -*- -%define with_xen 1 -%define with_xen_proxy 1 -%define with_qemu 1 -%define with_openvz 1 -%define with_lxc 1 -%define with_polkit 0 +%define with_xen 0%{!?_without_xen:1} +%define with_xen_proxy 0%{!?_without_xen_proxy:1} +%define with_qemu 0%{!?_without_qemu:1} +%define with_openvz 0%{!?_without_openvz:1} +%define with_lxc 0%{!?_without_lxc:1} +%define with_sasl 0%{!?_without_sasl:1} +%define with_avahi 0%{!?_without_avahi:1} +%define with_polkit 0%{!?_without_polkit:0} +%define with_python 0%{!?_without_python:1} +%define with_libvirtd 0%{!?_without_libvirtd:1} +%define with_devel 0%{!?_without_devel:1} # Xen is available only on i386 x86_64 ia64 %ifnarch i386 i686 x86_64 ia64 @@ -23,7 +28,7 @@ %endif %if 0%{fedora} >= 8 -%define with_polkit 1 +%define with_polkit 0%{!?_without_polkit:1} %define with_xen_proxy 0 %endif @@ -46,10 +51,12 @@ Requires: iptables # So remote clients can access libvirt over SSH tunnel # (client invokes 'nc' against the UNIX socket on the server) Requires: nc +%if %{with_sasl} Requires: cyrus-sasl # Not technically required, but makes 'out-of-box' config # work correctly & doesn't have onerous dependencies Requires: cyrus-sasl-md5 +%endif %if %{with_polkit} Requires: PolicyKit >= 0.6 %endif @@ -82,14 +89,18 @@ BuildRequires: readline-devel BuildRequires: ncurses-devel BuildRequires: gettext BuildRequires: gnutls-devel +%if %{with_avahi} BuildRequires: avahi-devel +%endif BuildRequires: libselinux-devel BuildRequires: dnsmasq BuildRequires: bridge-utils %if %{with_qemu} BuildRequires: qemu %endif +%if %{with_sasl} BuildRequires: cyrus-sasl-devel +%endif %if %{with_polkit} BuildRequires: PolicyKit-devel >= 0.6 %endif @@ -119,6 +130,7 @@ BuildRequires: gawk Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). +%if %{with_devel} %package devel Summary: Libraries, includes, etc. to compile with the libvirt library Group: Development/Libraries @@ -132,7 +144,9 @@ Obsoletes: libvir-devel %description devel Includes and documentations for the C library providing an API to use the virtualization capabilities of recent versions of Linux (and other OSes). +%endif +%if %{with_python} %package python Summary: Python bindings for the libvirt library Group: Development/Libraries @@ -144,6 +158,7 @@ The libvirt-python package contains a module that permits applications written in the Python programming language to use the interface supplied by the libvirt library to use the virtualization capabilities of recent versions of Linux (and other OSes). +%endif %prep %setup -q @@ -190,6 +205,7 @@ install -d -m 0755 $RPM_BUILD_ROOT%{_localstatedir}/lib/libvirt/images/ # Default dir for kernel+initrd images defnied in SELinux policy install -d -m 0755 $RPM_BUILD_ROOT%{_localstatedir}/lib/libvirt/boot/ +%if %{with_qemu} # We don't want to install /etc/libvirt/qemu/networks in the main %files list # because if the admin wants to delete the default network completely, we don't # want to end up re-incarnating it on every RPM upgrade. @@ -200,14 +216,33 @@ rm -f $RPM_BUILD_ROOT%{_sysconfdir}/libvirt/qemu/networks/default.xml rm -f $RPM_BUILD_ROOT%{_sysconfdir}/libvirt/qemu/networks/autostart/default.xml # Strip auto-generated UUID - we need it generated per-install sed -i -e "/<uuid>/d" $RPM_BUILD_ROOT%{_datadir}/libvirt/networks/default.xml +%endif %find_lang %{name} +# If we are not building with certain options, we need to remove files +# so that we don't get Installed (but unpackaged) errors +%if !

[libvirt] [PATCH] kvm: maxVCPU runtime detection
by Guido Günther 17 Sep '08

17 Sep '08

Hi, with recent linux kernels we can detect the maximum number of virtual cpus at runtime via an ioctl. Possible patch attached. It does this on every call to qemudGetMaxVCPUs. Would you prefer something that does this only once in qemudStartup()? Cheers, -- Guido

[libvirt] network domain name patch
by JJ Reynolds 16 Sep '08

16 Sep '08

Hi all, This is a followup to the excellent patch which allows static IP address assignment. The problem with that patch is that you can only set the host name and cannot set a FQDN because dnsmasq will, as a security measure, not allow it unless --domain is specified. This patch adds support for adding <domain name="my.domain" /> to the network config file. With that stanza, one can then use FQDNs on the static host assignments, and this should be the domain reported for any clients that request it. If <domain name .. ./> is not specified in the config file, then there is no change in behaviour. As a special case, you can also set the domain name to "#", whereupon dnsmasq interprets that to use the domain of the host OS. Example default.xml: <network> <name>default</name> <uuid>0098abb7-ff94-4df9-aa78-e4c3fe636a3d</uuid> <bridge name="virbr0" /> <domain name="mynet.net" /> <forward/> <ip address="192.168.122.1" netmask="255.255.255.0"> <dhcp> <host name="vm1.mynet.net" mac="00:16:3e:24:a5:84" ip="192.168.122.101" /> <host name='vm2.mynet.net' mac="00:16:3e:1f:9a:95" ip="192.168.122.102" /> <range start="192.168.122.2" end="192.168.122.99" /> </dhcp> </ip> </network> Here is the patch: diff -r -U 3 libvirt-0.4.4/src/network_conf.c libvirt-0.4.4jjr/src/network_conf.c --- libvirt-0.4.4/src/network_conf.c 2008-08-20 09:20:01.000000000 -0400 +++ libvirt-0.4.4jjr/src/network_conf.c 2008-09-06 14:03:56.000000000 -0400 @@ -326,6 +326,9 @@ VIR_FREE(tmp); } + /* Parse network domain information */ + def->domain = virXPathString(conn, "string(./domain[1]/@name)", ctxt); + /* Parse bridge information */ def->bridge = virXPathString(conn, "string(./bridge[1]/@name)", ctxt); tmp = virXPathString(conn, "string(./bridge[1]/@stp)", ctxt); diff -r -U 3 libvirt-0.4.4/src/network_conf.h libvirt-0.4.4jjr/src/network_conf.h --- libvirt-0.4.4/src/network_conf.h 2008-08-20 09:20:01.000000000 -0400 +++ libvirt-0.4.4jjr/src/network_conf.h 2008-09-06 14:03:56.000000000 -0400 @@ -57,6 +57,7 @@ char *name; char *bridge; /* Name of bridge device */ + char *domain; unsigned long delay; /* Bridge forward delay (ms) */ int stp : 1; /* Spanning tree protocol */ diff -r -U 3 libvirt-0.4.4/src/qemu_driver.c libvirt-0.4.4jjr/src/qemu_driver.c --- libvirt-0.4.4/src/qemu_driver.c 2008-08-29 03:20:02.000000000 -0400 +++ libvirt-0.4.4jjr/src/qemu_driver.c 2008-09-06 14:15:28.000000000 -0400 @@ -1105,6 +1105,7 @@ 1 + /* --keep-in-foreground */ 1 + /* --strict-order */ 1 + /* --bind-interfaces */ + (network->def->domain?2:0) + /* --domain name */ 2 + /* --pid-file "" */ 2 + /* --conf-file "" */ /*2 + *//* --interface virbr0 */ @@ -1136,6 +1137,11 @@ APPEND_ARG(*argv, i++, "--strict-order"); APPEND_ARG(*argv, i++, "--bind-interfaces"); + if (network->def->domain) { + APPEND_ARG(*argv, i++, "--domain"); + APPEND_ARG(*argv, i++, network->def->domain); + } + APPEND_ARG(*argv, i++, "--pid-file"); APPEND_ARG(*argv, i++, ""); Thanks! -JJ Reynolds

[libvirt] LXC: making the private root filesystem more secure
by Daniel P. Berrange 12 Sep '08

12 Sep '08

When I wrote the private root filesystem stuff for LXC (which I just committed) I noted that we couldn't actually make this secure, because someone inside the chroot can just 'mknod' and access the host devices. What I completely forgot was that cgroups as of 2.6.26 has device ACLs If we place every container in a cgroup (which was planned anyway), then we can trivially prevent containers accessing host devices One time setup mount -t cgroups /dev/cgroups mkdir /dev/cgroups/libvirt mkdir /dev/cgroups/libvirt/lxc For each new container 'NAME' mkdir /dev/cgroups/libvirt/lxc/{NAME} echo "a" > /dev/cgroups/libvirt/lxc/{NAME}/devices.deny echo "c 1:3 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow echo "c 1:5 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow echo "c 1:7 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow echo "c 5:1 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow echo "c 1:8 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow echo "c 1:9 rwm" > /dev/cgroups/libvirt/lxc/{NAME}/devices.allow This denies all devices, and then allows null, zero, full, console, random and urandom. Allowing use of 'random' is debatable. The 'devpts' namespace stuff is also needed to provide private PTYs. The 'user' namespace stuff is needed to prevent an unprivileged user in the host OS from killing off processes with same UID inside the container. There looks to be active patchsets for both of these being discussed, so we're getting close to having a genuinely useful container based virt driver with LXC Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://ovirt.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :|

[libvirt] virDomainGetInfo() returns 0 although the domain is not running anymore
by Johannes Formann 12 Sep '08

12 Sep '08

Hello, if I understand the API-documentation, virDomainGetInfo() should return -1 when the domain does not exists anymore, or some other problem happens. But with this code below ... if (virDomainGetInfo(domainPtr,domainInfo) == 0 ) { if (debugLevel > 15) {puts("virDomainGetInfo() returns 0");} if (domainInfo->state == VIR_DOMAIN_NOSTATE || domainInfo->state == VIR_DOMAIN_RUNNING || domainInfo->state == VIR_DOMAIN_BLOCKED || domainInfo->state == VIR_DOMAIN_PAUSED ) { return(false); } } ... I notized, virDomainGetInfo() always returns zero, even if libvirt prints an error. If I destroy a domain (xm destroy) I'll get this Message with each call of virDomainGetInfo(): "libvir: Xen Daemon error : GET operation failed:" But virDomainGetInfo() still returns zero, a bug, or did I missunderstood the API? regards Johannes

[libvirt] [PATCH] Fix segfault if no qemu emulator passed
by Cole Robinson 12 Sep '08

12 Sep '08

There is unfortunately a pretty prevalent segfault in the latest libvirt. If a qemu domain is defined without an emulator specified, libvirtd crashes. This is doubly unfortunate since current virtinst generates an emulator-less config for all qemu and kvm guests (I'm about to fix this upstream though). Attached patch fixes this. Thanks, Cole diff --git a/src/qemu_conf.c b/src/qemu_conf.c index d742c32..23ef050 100644 --- a/src/qemu_conf.c +++ b/src/qemu_conf.c @@ -790,7 +790,7 @@ int qemudBuildCommandLine(virConnectPtr conn, if (!emulator) return -1; - ADD_ARG_LIT(vm->def->emulator); + ADD_ARG_LIT(emulator); ADD_ARG_LIT("-S"); ADD_ARG_LIT("-M"); ADD_ARG_LIT(vm->def->os.machine);

[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.

[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.

[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

[libvirt] [PATCH] Implement vol delete for disk pools
by Cole Robinson 08 Sep '08

08 Sep '08

The patch below implements virStorageVolDelete for volumes on a disk pool. The only interesting thing here is that parted wants a partition number to delete, so we need to peel off the end of the volume's target path which will be of the form '/dev/sda1' or similar (I assume. If not, it's still better than having nothing implemented). Thanks, Cole
