Note: I haven't tried building this on Linux yet, so we may have some #ifdef or Makefile changes on non-Solaris platforms. Please Cc: Eunice.Moon@Sun.COM on any response. Thanks, Ryan LDoms Support This patch adds the Logical Domains (LDoms) support for the SPARC platforms. LDoms software is Sun Microsystem's virtualization technology to subdivide a supported system's resources (CPUs, memory, I/O, and storage) creating partitions called logical domains. The Logical Domains Manager is used to create and manage logical domains and maps logical domains to physical resources. The LDoms Manager provides a command-line interface and also exports an XML-based control interface. The Libvirt for LDoms uses this XML interface to communicate with the LDoms Manager to retrieve the LDoms data for: - Listing domains - Requesting CPU and memory resource updates - Performing life-cycle actions for logical domains This libvirt patch supports LDoms 1.0.1 and 1.0.2. This patch will modify the following existing files: src/libvirt.c src/virsh.c src/virterror.c src/driver.h src/Makefile.am include/libvirt/libvirt.h.in include/libvirt/virterror.h configure.in and add the following new files: src/ldoms_common.h src/ldoms_internal.h src/ldoms_internal.c src/ldoms_intfc.h src/ldoms_intfc.c src/ldoms_xml_parse.h src/ldoms_xml_parse.c Signed-off-by: Eunice Moon <eunice.moon@sun.com> diff --git a/src/libvirt.c b/src/libvirt.c --- a/src/libvirt.c +++ b/src/libvirt.c @@ -48,6 +48,9 @@ #ifdef WITH_LXC #include "lxc_driver.h" #endif +#ifdef WITH_LDOMS +extern int ldomsRegister(void); +#endif /* * TODO: @@ -267,6 +270,11 @@ virInitialize(void) * Note that the order is important: the first ones have a higher * priority when calling virConnectOpen. */ +#ifdef WITH_LDOMS + if (ldomsRegister() == -1) return -1; + /* Don't want to run any other HV with LDoms */ + return (0); +#endif #ifdef WITH_TEST if (testRegister() == -1) return -1; #endif @@ -1794,11 +1802,17 @@ virDomainGetUUID(virDomainPtr domain, un return (-1); } +#ifndef WITH_LDOMS if (domain->id == 0) { memset(uuid, 0, VIR_UUID_BUFLEN); } else { memcpy(uuid, &domain->uuid[0], VIR_UUID_BUFLEN); } +#endif + +#ifdef WITH_LDOMS + memcpy(uuid, &domain->uuid[0], VIR_UUID_BUFLEN); +#endif return (0); } @@ -5025,6 +5039,42 @@ virStorageVolGetPath(virStorageVolPtr vo return NULL; } +#ifdef WITH_LDOMS +/** + * virLDomConsole: + * @domain: the domain if available + * + * Opens a terminal window to the console for a domain + * + * Returns -1 in case of error, LDom console port number in case of success + */ +int +virLDomConsole(virDomainPtr domain) +{ + virConnectPtr conn; + DEBUG("Starting domain %p", domain); + + if (domain == NULL) { + TODO + return (-1); + } + if (!VIR_IS_CONNECTED_DOMAIN(domain)) { + virLibDomainError(domain, VIR_ERR_INVALID_DOMAIN, __FUNCTION__); + return (-1); + } + conn = domain->conn; + if (conn->flags & VIR_CONNECT_RO) { + virLibDomainError(domain, VIR_ERR_OPERATION_DENIED, __FUNCTION__); + return (-1); + } + + if (conn->driver->ldomConsole) + return conn->driver->ldomConsole (domain); + + virLibConnError (conn, VIR_ERR_NO_SUPPORT, __FUNCTION__); + return -1; +} +#endif /* * vim: set tabstop=4: diff --git a/src/virsh.c b/src/virsh.c --- a/src/virsh.c +++ b/src/virsh.c @@ -494,6 +494,11 @@ cmdConsole(vshControl * ctl, vshCmd * cm virDomainPtr dom; int ret = FALSE; char *doc; +#ifdef WITH_LDOMS + int port; + char command[80]; +#endif + if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; @@ -501,6 +506,19 @@ cmdConsole(vshControl * ctl, vshCmd * cm if (!(dom = vshCommandOptDomain(ctl, cmd, "domain", NULL))) return FALSE; +#ifdef WITH_LDOMS + port = virLDomConsole(dom); + if (port > 0) { + sprintf(command, "%s %d &", + "/usr/X/bin/xterm -sb -sl 1000 -e telnet localhost ", port); + system(command); + return TRUE; + } + + vshError(ctl, FALSE, _("Failed to start console")); + return FALSE; +#endif + doc = virDomainGetXMLDesc(dom, 0); if (!doc) goto cleanup; @@ -1003,13 +1021,21 @@ cmdUndefine(vshControl * ctl, vshCmd * c */ static vshCmdInfo info_start[] = { {"syntax", "start <domain>"}, +#ifdef WITH_LDOMS + {"help", gettext_noop("start an inactive or bound domain")}, +#else {"help", gettext_noop("start a (previously defined) inactive domain")}, +#endif {"desc", gettext_noop("Start a domain.")}, {NULL, NULL} }; static vshCmdOptDef opts_start[] = { +#ifdef WITH_LDOMS + {"domain", VSH_OT_DATA, VSH_OFLAG_REQ, gettext_noop("name of the inactive or bound domain")}, +#else {"name", VSH_OT_DATA, VSH_OFLAG_REQ, gettext_noop("name of the inactive domain")}, +#endif {NULL, 0, 0, NULL} }; @@ -1019,17 +1045,26 @@ cmdStart(vshControl * ctl, vshCmd * cmd) virDomainPtr dom; int ret = TRUE; +#ifdef WITH_LDOMS + /* Need to send in the 'domain' option name instead of 'name' */ + if (!(dom = vshCommandOptDomainBy(ctl, cmd, "domain", NULL, VSH_BYNAME))) + return FALSE; +#else if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; +#endif if (!(dom = vshCommandOptDomainBy(ctl, cmd, "name", NULL, VSH_BYNAME))) return FALSE; + /* Allow LDoms domain state to be inactive or bound */ +#ifndef WITH_LDOMS if (virDomainGetID(dom) != (unsigned int)-1) { vshError(ctl, FALSE, "%s", _("Domain is already active")); virDomainFree(dom); return FALSE; } +#endif if (virDomainCreate(dom) == 0) { vshPrint(ctl, _("Domain %s started\n"), @@ -1660,11 +1695,13 @@ cmdVcpuinfo(vshControl * ctl, vshCmd * c vshPrint(ctl, "%-15s %.1lfs\n", _("CPU time:"), cpuUsed); } +#ifndef WITH_LDOMS vshPrint(ctl, "%-15s ", _("CPU Affinity:")); for (m = 0 ; m < VIR_NODEINFO_MAXCPUS(nodeinfo) ; m++) { vshPrint(ctl, "%c", VIR_CPU_USABLE(cpumap, cpumaplen, n, m) ?
