[libvirt] PATCH: Domain XML import/export from/to native formats

This is an initial patch providing an API to import and export the Domain XML from/to native hypervisor formats. This implementation provides - Import from Xen XM config file format - Export to Xen XM config file format - Import from Xen SEXPR format - Export to Xen SEXPR format - Export to QEMU argv list Still todo is the more complex, - Import from QEMU argv list which is actually the most interesting & useful one, since that helps people currently using QEMU migrate over to using libvirt. The two new public APIs are /** * virConnectImportDomainXML: * @conn: a connection object * @format: configuration format importing from * @config: the configuration data to import * @flags: currently unused, pass 0 * * Reads native configuration data describing a domain, and * generates libvirt domain XML. The format of the native * data is hypervisor dependant. * * Returns a 0 terminated UTF-8 encoded XML instance, or NULL in case of error. * the caller must free() the returned value. */ char * virConnectImportDomainXML(virConnectPtr conn, const char *format, const char *config, unsigned int flags); /** * virConnectExportDomainXML: * @conn: a connection object * @format: configuration format exporting to * @xml: the domain configuration to export * @flags: currently unused, pass 0 * * Reads a domain XML configuration document, and generates * generates a native configuration file describing the domain. * The format of the native data is hypervisor dependant. * * Returns a 0 terminated UTF-8 encoded native config datafile, or NULL in case of error. * the caller must free() the returned value. */ char * virConnectExportDomainXML(virConnectPtr conn, const char *format, const char *xml, unsigned int flags); This is integrated via virsh eg import a Xen SEXPR config to libvirt domain XML # virsh import-domxml xen-sxpr demo.sxpr <domain type='xen' id='78'> <name>rhel5pv</name> <uuid>8f07fe28-753f-2729-d76d-bdbd892f949a</uuid> <memory>2560000</memory> <currentMemory>307200</currentMemory> ...snip rest... <graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'/> </devices> </domain> eg, export libvirt domain XML to Xen SEXPR format # virsh export-domxml xen-sxpr demo.xml (vm (name 'Xen')(memory 256)(maxmem 256)(vcpus 1) (uuid '971784f4-523b-1a8c-99eb-7e66a539c3ac') ...snip... (script 'vif-bridge')))) eg import a Xen XM config file # virsh import-domxml xen-xm demo.cfg <domain type='xen'> <name>rhel5pv</name> <uuid>8f07fe28-753f-2729-d76d-bdbd892f949a</uuid> <memory>2560000</memory> <currentMemory>307200</currentMemory> <vcpu>4</vcpu> <bootloader>/usr/bin/pygrub</bootloader> ....snip... </domain> eg export to Xen XM config file # virsh export-domxml xen-xm demo.xml name = "Xen" uuid = "971784f4-523b-1a8c-99eb-7e66a539c3ac" maxmem = 256 memory = 256 vcpus = 1 kernel = "/var/lib/xen/vmlinuz" ...snip... vif = [ "mac=00:16:3e:53:45:a9,bridge=virbr0" ] eg export to QEMU ARGV format # virsh -c qemu:///session export-domxml qemu-argv ~/rhel5xen.xml LC_ALL=C LD_LIBRARY_PATH=/home/berrange/usr/lib PATH=/usr/bin:/bin HOME=/home/berrange USER=berrange LOGNAME=berrange /usr/bin/qemu-kvm -S -M pc -m 1967 -smp 4 -name rhel5xen -uuid be8b4f9a-492a-db25-7aed-f831dcec9127 -monitor pty -pidfile /home/berrange/.libvirt/qemu/run/rhel5xen.pid -boot c -drive file=/dev/HostVG/rhel5xen,if=ide,index=0,boot=on -net nic,macaddr=00:16:3e:09:f2:eb,vlan=0 -net tap,vlan=0 -net nic,macaddr=00:16:3e:09:f3:eb,vlan=1 -net tap,vlan=1 -net nic,macaddr=00:16:3e:09:f4:eb,vlan=2 -net tap,vlan=2 -net nic,macaddr=00:16:3e:09:f5:eb,vlan=3 -net tap,vlan=3 -serial file:/tmp/rhel5xen.log -parallel none -usb -vnc 0.0.0.0:0 -k en-us The import thing to note here is that the import/export process is done via the real libvirt drivers, but the destination / source configs are not loaded into the hypervisor / mangement app at all. It is purely a put a string in, get a string out process. What you do with the generated config is up to you. Also note that you can't export a Xen config using the QEMU driver, and vica-verca. The openvz, test, uml drivers don't implement these new APIs, though openvz & uml could be made to. The Remote driver & daemon is implemented here, and python bindings are provided too. docs/devhelp/libvirt-libvirt.html | 12 ++ docs/html/libvirt-libvirt.html | 8 + docs/libvirt-api.xml | 20 ++++ docs/libvirt-refs.xml | 158 +++++++++++++++++++++++++------------ include/libvirt/libvirt.h | 10 ++ include/libvirt/libvirt.h.in | 10 ++ qemud/remote.c | 34 +++++++ qemud/remote_dispatch_args.h | 2 qemud/remote_dispatch_prototypes.h | 14 +++ qemud/remote_dispatch_ret.h | 2 qemud/remote_dispatch_table.h | 14 ++- qemud/remote_protocol.c | 44 ++++++++++ qemud/remote_protocol.h | 34 +++++++ qemud/remote_protocol.x | 27 ++++++ src/driver.h | 12 ++ src/libvirt.c | 99 +++++++++++++++++++++++ src/libvirt_public.syms | 6 + src/lxc_driver.c | 2 src/openvz_driver.c | 2 src/qemu_conf.c | 25 ++--- src/qemu_conf.h | 3 src/qemu_driver.c | 127 +++++++++++++++++++++++++++++ src/remote_internal.c | 64 ++++++++++++++ src/test.c | 2 src/uml_driver.c | 2 src/virsh.c | 94 ++++++++++++++++++++++ src/xen_unified.c | 93 +++++++++++++++++++++ src/xen_unified.h | 3 28 files changed, 853 insertions(+), 70 deletions(-) Daniel diff -r ba47cd6949a4 docs/devhelp/libvirt-libvirt.html --- a/docs/devhelp/libvirt-libvirt.html Thu Apr 16 12:44:17 2009 +0100 +++ b/docs/devhelp/libvirt-libvirt.html Fri Apr 17 10:22:22 2009 +0100 @@ -126,6 +126,7 @@ int <a href="#virNodeDeviceDettach">virN int <a href="#virDomainGetSecurityLabel">virDomainGetSecurityLabel</a> (<a href="libvirt-libvirt.html#virDomainPtr">virDomainPtr</a> domain, <br/> <a href="libvirt-libvirt.html#virSecurityLabelPtr">virSecurityLabelPtr</a> seclabel);
