[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. 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(!)

[libvirt] ANNOUNCE: New release virtinst 0.400.0
by Cole Robinson 10 Sep '08

10 Sep '08

I'm happy to announce a new virtinst release, version 0.400.0. It can be downloaded at: http://virt-manager.org/download.html The direct link is: http://virt-manager.org/download/sources/virtinst/virtinst-0.400.0.tar.gz New in this release: - New tool 'virt-convert': Allows converting between different types of virt configuration files. Currently only supports vmx -> virt-image. - New tool 'virt-pack': Converts virt-image xml format to vmx and packs in a tar.gz. (Note this will likely be merged with virt-convert in the future). - virt-install: Support for remote VM installation. Can use install media and disk images on remote host if shared via libvirt. Allows provisioning storage on remote pools. - virt-install new options: new --wait option, allows putting a hard time limit on installs. new --sound option, to create VM with soundcard emulation. new --disk option, allows specifying media as a path, storage volume, or a pool to provision storage on, device type, and several other options. Deprecates --file, --size, --nonsparse. new --prompt option. Input prompting is no longer the default, this option turns it back on. - virt-install: allow setting cpu pinning information for qemu/kvm VMs. - virt-install: numa support via --cpuset=auto option. - virt-image: --replace option to overwrite existing VM image file. - virt-image: support multiple network interfaces in virt-image format. - use virtio disk/net drivers if chosen os entry supports it (Fedora 9/10, Ubuntu Hardy). - Numerous bug fixes and minor improvements. Thanks to everyone who has contributed to this release whether by testing, bug reporting, submitting patches, and otherwise sending feedback! Thanks, Cole
