New subject: [libvirt] [PATCH v7 1/8] parallels: add driver skeleton

Parallels Cloud Server is a virtualization solution that allows users to simultaneously run multiple virtual machines and containers on the same physical server. More information can be found here: http://www.parallels.com/products/pcs/ Also beta version of Parallels Cloud Server can be downloaded there. This first patch adds driver, which can report node info only. Signed-off-by: Dmitry Guryanov <dguryanov(a)parallels.com> --- changes in v7: * renamed to 'parallels', because first, the product renamed to "Parallels Cloud Server" and there are other products, such as Parallels Workstation for linux, which this driver will be able operate. changes in v6: * Add info about PVS to commit message * fixed issue with POTFILES.in * fixed check in configure * check for prlctl command existence moved to pvsRegister changes in v5: * add me to AUTHORS * fix indent in preprocessor directives in pvs_driver.h * remove unneded include * remove pvs_driver.c from po/POTFILES.in cfg.mk | 1 + configure.ac | 23 ++++ docs/drvparallels.html.in | 28 ++++ include/libvirt/virterror.h | 2 +- libvirt.spec.in | 9 +- mingw32-libvirt.spec.in | 6 + po/POTFILES.in | 1 + src/Makefile.am | 13 ++ src/conf/domain_conf.c | 3 +- src/conf/domain_conf.h | 1 + src/driver.h | 1 + src/libvirt.c | 9 ++ src/parallels/parallels_driver.c | 271 ++++++++++++++++++++++++++++++++++++++ src/parallels/parallels_driver.h | 51 +++++++ src/util/virterror.c | 3 +- 15 files changed, 418 insertions(+), 4 deletions(-) create mode 100644 docs/drvparallels.html.in create mode 100644 src/parallels/parallels_driver.c create mode 100644 src/parallels/parallels_driver.h diff --git a/cfg.mk b/cfg.mk index 7664d5d..7efe6a7 100644 --- a/cfg.mk +++ b/cfg.mk @@ -513,6 +513,7 @@ msg_gen_function += PHYP_ERROR msg_gen_function += VIR_ERROR msg_gen_function += VMX_ERROR msg_gen_function += XENXS_ERROR +msg_gen_function += PARALLELS_ERROR msg_gen_function += eventReportError msg_gen_function += ifaceError msg_gen_function += interfaceReportError diff --git a/configure.ac b/configure.ac index 3da1aa2..6ed7a2f 100644 --- a/configure.ac +++ b/configure.ac @@ -330,6 +330,8 @@ AC_ARG_WITH([esx], AC_HELP_STRING([--with-esx], [add ESX support @<:@default=check@:>@]),[],[with_esx=check]) AC_ARG_WITH([hyperv], AC_HELP_STRING([--with-hyperv], [add Hyper-V support @<:@default=check@:>@]),[],[with_hyperv=check]) +AC_ARG_WITH([parallels], + AC_HELP_STRING([--with-parallels], [add Parallels Virtuozzo Server support @<:@default=check@:>@]),[],[with_parallels=check]) AC_ARG_WITH([test], AC_HELP_STRING([--with-test], [add test driver support @<:@default=yes@:>@]),[],[with_test=yes]) AC_ARG_WITH([remote], @@ -788,6 +790,26 @@ fi AM_CONDITIONAL([WITH_LXC], [test "$with_lxc" = "yes"]) dnl +dnl Checks for the PARALLELS driver +dnl + +if test "$with_parallels" = "check"; then + with_parallels=$with_linux + if test ! $host_cpu = 'x86_64'; then + with_parallels=no + fi +fi + +if test "$with_parallels" = "yes" && test "$with_linux" = "no"; then + AC_MSG_ERROR([The PARALLELS driver can be enabled on Linux only.]) +fi + +if test "$with_parallels" = "yes"; then + AC_DEFINE_UNQUOTED([WITH_PARALLELS], 1, [whether PARALLELS driver is enabled]) +fi +AM_CONDITIONAL([WITH_PARALLELS], [test "$with_parallels" = "yes"]) + +dnl dnl check for shell that understands <> redirection without truncation, dnl needed by src/qemu/qemu_monitor_{text,json}.c. dnl @@ -2805,6 +2827,7 @@ AC_MSG_NOTICE([ LXC: $with_lxc]) AC_MSG_NOTICE([ PHYP: $with_phyp]) AC_MSG_NOTICE([ ESX: $with_esx]) AC_MSG_NOTICE([ Hyper-V: $with_hyperv]) +AC_MSG_NOTICE([ PARALLELS: $with_parallels]) AC_MSG_NOTICE([ Test: $with_test]) AC_MSG_NOTICE([ Remote: $with_remote]) AC_MSG_NOTICE([ Network: $with_network]) diff --git a/docs/drvparallels.html.in b/docs/drvparallels.html.in new file mode 100644 index 0000000..976dea1 --- /dev/null +++ b/docs/drvparallels.html.in @@ -0,0 +1,28 @@ +<html><body> + <h1>Parallels Virtuozzo Server driver</h1> + <ul id="toc"></ul> + <p> + The libvirt PARALLELS driver can manage Parallels Virtuozzo Server starting from 6.0 version. + </p> + + + <h2><a name="project">Project Links</a></h2> + <ul> + <li> + The <a href="http://www.parallels.com/products/server/baremetal/sp/"&g...

New subject: [libvirt] [PATCH v7 2/8] parallels: add functions to list domains and get info

Parallels driver is 'stateless', like vmware or openvz drivers. It collects information about domains during startup using command-line utility prlctl. VMs in Parallels Cloud Server are identified by UUIDs or unique names, which can be used as respective fields in virDomainDef structure. Currently only basic info, like description, virtual cpus number and memory amount, is implemented. Querying devices information will be added in the next patches. Parallels Cloud Server doesn't support non-persistent domains - you can't run a domain having only disk image, it must always be registered in system. Functions for querying domain info have been just copied from test driver with some changes - they extract needed data from previously created list of virDomainObj objects.

New subject: [libvirt] [PATCH v7 6/8] parallels: implement virDomainDefineXML operation for existing domains

Add parallelsDomainDefineXML function, it works only for existing domains for the present. It's too hard to convert libvirt's XML domain configuration into parallels's one, so I've decided to compare virDomainDef structures: current domain definition and the one created from XML, given to the function. And change only different parameters. Only description change implemetented, changing other parameters will be implemented later.

New subject: [libvirt] [PATCH v7 7/8] parallels: add storage driver

Parallels Cloud Server has one serious discrepancy with libvirt: libvirt stores domain configuration files in one place, and storage files in other places (with the API of storage pools and storage volumes). Parallels Cloud Server stores all domain data in a single directory, for example, you may have domain with name fedora-15, which will be located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be in '/var/parallels/fedora-15.pvm/harddisk1.hdd'. I've decided to create storage driver, which produces pseudo-volumes (xml files with volume description), and they will be 'converted' to real disk images after attaching to a VM. So if someone creates VM with one hard disk using virt-manager, at first virt-manager creates a new volume, and then defines a domain. We can lookup a volume by path in XML domain definition and find out location of new domain and size of its hard disk.

New subject: [libvirt] [PATCH v7 8/8] parallels: implement VM creation

To create a new VM in Parallels Clud Server we should issue "prlctl create" command, and give path to the directory, where VM should be created. VM's storage will be in that directory later. So in this first version find out location of first VM's hard disk and create VM there.

I woud not rush it to push it before the freeze, it's a big new functionality and i would rather have a bit of time before a release with it. But starting next week we should be good to go commiting the parts of the drivers which would get ACK'ed in the meantime. thanks !

I'd suggest when we merge the Parallels driver, we can change our version number to be 0.10.0, since we've been on 0.9.x for a long time now, and new hypervisor drivers have been our motivation for version number changes in the past :-) Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :|

Okay, this should affect patches 2,3,6 and 7 where 0.9.12 will have to be replaced by 0.10.0, but that can be done easilly when this gets applied to the tree next week, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Thanks a lot ! I think it's better for me to wait for comments until next week before writing new code :) -- Dmitry Guryanov

It was actually just renamed to mingw-libvirt.spec.in - and re-arranged to build for 32 & 64 bit Windows binaries. You ought to be able to adapt your change to apply to the new file without much trouble.
