The project requests minor binding. Libvirt for LDoms (Logical Domains) support =========================================== ARC Exposure: open 1. Background The Libvirt for LDoms software to provide libvirt interfaces for LDoms hypervisor was already released at Sun Download Center [1]. The LDoms support was added to libvirt version 0.3.2 and virtinst version 0.103.0, and was released as the Solaris 10 packages to support LDoms 1.0.1 and 1.0.2. This fast-track RFE will add the same LDoms support to libvirt version 0.4.0 which was put back to the Nevada xVM gate with Xen 3.1.2 and virtinst version 0.300.1 which will be put back soon. The purpose of this RFE is to provide the Libvirt for LDoms support for use in Open Solaris environment and will be put back to the Nevada xVM gate. It is not targeting an S10 putback. It is just targeting for the Nevada xVM gate (/ws/xvm-gate) for use in Open Solaris environment. [1] - Libvirt for LDoms 1.0.1 is available for customer download at: http://www.sun.com/servers/coolthreads/ldoms/get.jsp Please see the References section below for the available documentation for Libvirt for LDoms 1.0.1. 2. Overview Libvirt is an open source management library that interacts with virtualization capabilities. The libvirt for LDoms software will add the LDoms driver as a supported hypervisor in the libvirt driver system. With the LDoms support, the libvirt library will interact with the LDoms Manager software via its XML-based control interface to retrieve the LDoms data or request CPU/memory resource updates. It will also support some lifecycle commands (such as create, start, destroy, ..etc) on the guest domain. virsh is included in libvirt. virsh is built on top of libvirt and allows a user to interact with the hypervisor and guest domains. With the LDoms support, a user can run virsh to interact with the LDoms hypervisor as below: /usr/bin/virsh -c ldoms:///default virt-install will allow a user to install a guest operating system on LDoms system: /usr/sbin/virt-install --connect=ldoms:///default 3. Library Interfaces The LDoms Manager provides a command-line interface and also exports a XML based control interface. The libvirt LDoms driver will use this XML interface to communicate with the LDoms Manager to retrieve the LDoms data and request the CPU/memory resource updates or LDoms life cycle actions. The current (version 1.0.1 and 1.0.2) LDoms Manager's XML interface is using the socket connection. ---------------------------------------------------------------------------- | Imported Interface | Stability | Comments | +-----------------------------+-----------------+--------------------------+ | LDoms Manager 1.0.1/1.0.2 | Consolidation | LDoms Libvirt bundled with| | XML/CLI interfaces | Private | LDoms Manager | +-----------------------------+-------------------------+------------------+ ---------------------------------------------------------------------------- | exported Interface | Stability | Comments | +-------------------------------+---------------------+--------------------+ | libvirt/virsh | Volatile | Updated to support | | | | LDoms | +-------------------------------+---------------------+--------------------+ | virt-install | Volatile | Updated to support | | | | LDoms | +-------------------------------+---------------------+--------------------+ 4.

Supported virt-install Options The following virt-install options will be supported for LDoms. -n NAME, --name=NAME Name of the guest instance -r MEMORY, --ram=MEMORY Memory to allocate for guest instance --vcpus=VCPUS Number of vcpus to configure for your guest --check-cpu Check that vcpus do not exceed physical CPUs -f DISKFILE, --file=DISKFILE File to use as the disk image -s DISKSIZE, --file-size=DISKSIZE Size of the disk image -m MAC, --mac=MAC Fixed MAC address for the guest --connect=CONNECT Connect to hypervisor with URI -d, --debug Print debugging information -h, --help show help message 6.

It's perhaps not beautiful, but is there any reason libvirt can't do something like: #ifdef __sparc if (connect == NULL) connect = "ldoms:///default/"; #endif It just seems strange to default to something that can't work. > >What happens if a non-supported virsh command is run? > User will get the 'unknown command' error since the non-supported > virsh commands are listed under #ifndef WITH_LDOMS block in > the vshCmdDef/commands[] data structure.

It currently also supports QEMU, KVM and OpenVZ. So, xen is the default hypervisor and users would specify any other hypervisor as the command line options (with --connect) if they want to connect to any other hypervisor than xen.

I can't, BTW, find such a manpage at libvirt.org, not without actually downloading the source. Searching the 'Net I can find it. The answer to Roland's question is that virsh is a shell, just not in the sense that he thinks of "shell" -- it's a shell in the same sense that the sqlite3(1) program is a shell: an interactive, text-based interface to a complex feature.

I don't think the man page needs to be changed for this case, so I didn't think it was necessary to include it. We can include a copy if you want. We probably should have included the man page changes in 2008/165, but that is an entirely different discussion. > > I can't, BTW, find such a manpage at libvirt.org, not without actually > downloading the source.

With respect, this doesn't answer my question. I'm aware of what libvirt *can* do. I'm asking for a reason to default to a known broken behaviour on SPARC platforms, or a modification of the case to default to ldoms. (As an analogy: if libvirt 3.0 or whatever defaulted to KVM, we'd change it so the Solaris version defaulted to xVM/Xen.) regards john From Eunice.Moon@sun.com Mon Apr 7 12:32:20 2008 Received: from sunmail3mpk.sfbay.sun.com (sunmail3mpk.SFBay.Sun.COM [129.146.11.52]) by sac.sfbay.sun.com (8.13.8+Sun/8.13.8) with ESMTP id m37JWJPm027547 for ; Mon, 7 Apr 2008 12:32:20 -0700 (PDT) Received: from nwk-avmta-2.sfbay.sun.com (nwk-avmta-2.SFBay.Sun.COM [129.145.155.6]) by sunmail3mpk.sfbay.sun.com (8.13.7+Sun/8.13.7/ENSMAIL,v2.2) with ESMTP id m37JWIeZ026819; Mon, 7 Apr 2008 12:32:18 -0700 (PDT) Received: from pmxchannel-daemon.nwk-avmta-2.sfbay.sun.com by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) id <0JYY00M25ZLTBF00@nwk-avmta-2.sfbay.sun.com>; Mon, 07 Apr 2008 12:32:17 -0700 (PDT) Received: from brmea-mail-2.sun.com ([192.18.98.43]) by nwk-avmta-2.sfbay.sun.com (Sun Java System Messaging Server 6.2-3.04 (built Jul 15 2005)) with ESMTP id <0JYY00DAIZLSO2F0@nwk-avmta-2.sfbay.sun.com>; Mon, 07 Apr 2008 12:32:16 -0700 (PDT) Received: from fe-amer-09.sun.com ([192.18.109.79]) by brmea-mail-2.sun.com (8.13.6+Sun/8.12.9) with ESMTP id m37JWGMh010494; Mon, 07 Apr 2008 19:32:16 +0000 (GMT) Received: from conversion-daemon.mail-amer.sun.com by mail-amer.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) id <0JYY00M01Y4ICO00@mail-amer.sun.com> (original mail from Eunice.Moon@Sun.COM); Mon, 07 Apr 2008 13:32:16 -0600 (MDT) Received: from [129.153.131.86] by mail-amer.sun.com (Sun Java System Messaging Server 6.2-8.04 (built Feb 28 2007)) with ESMTPSA id <0JYY00800ZLGWXG0@mail-amer.sun.com>; Mon, 07 Apr 2008 13:32:04 -0600 (MDT) Date: Mon, 07 Apr 2008 14:32:01 -0500 From: Eunice Moon Subject: Re: PSARC/2008/237 Libvirt for LDoms support In-reply-to: <20080407182841.GB26587@barman.uk.sun.com> Sender: Eunice.Moon@sun.com To: John Levon Cc: Dan Hain , PSARC-ext@sun.com, Ryan Scott Message-id: <47FA76B1.9040908@Sun.COM> MIME-version: 1.0 Content-type: text/plain; format=flowed; charset=ISO-8859-1 Content-transfer-encoding: 7BIT X-PMX-Version: 5.4.1.325704 References: <47F6A3D5.7090206@sun.com> <20080406185449.GA13155@barman.uk.sun.com> <47FA316A.6050900@Sun.COM> <20080407160615.GC20546@barman.uk.sun.com> <47FA62A7.3030907@Sun.COM> <20080407182841.GB26587@barman.uk.sun.com> User-Agent: Thunderbird 2.0.0.6 (X11/20070802) Status: RO Content-Length: 1143 Hi John, Yes, I can change the code to make default to ldoms for SPARC platforms.

I will make the code changes to default to ldoms on the SPARC platform if user doesn't specify with --connect. I will include a copy of man page. This doesn't include the virt-manager tool. virt-manager is done by the JDS team as a separate project. Please see http://sac.sfbay/Archives/CaseLog/arc/LSARC/2007/175/ libvirt will be installed on the control domain where the LDoms Manager is running and it can't be managed by a remote system.
