[Libvir] [PATCH] header file changes for Solaris
by Mark Johnson 16 Jun '07

16 Jun '07

This patch has the includes need to build on Solaris. I've been using ifdef linux & ifndef linux to distinguish between solaris and linux at this point. I'm not sure what the preference is... MRJ

[Libvir] [PATCH] Solaris dom0 support
by Mark Johnson 15 Jun '07

15 Jun '07

This is a little bigger of a patch. It has a couple of things in it. First, in xen_internal.c and xs_internal.c have general dom0 support for Solaris. Again, using #ifdef/ifndef __linux__ to separate the logic. In xml.c and xend_internal.c, the code which requires kernel to be defined if ifdef __linux__'d. For our setup, If bootloader, kernel, and ramdisk aren't defined, pygrub will got looking for the right bits. There also code which puts in the the vncpasswd in xend_internal.c. This is the last patch I'll send out for today... Mark

[Libvir] libvirt ./configure
by Mark Johnson 15 Jun '07

15 Jun '07

Just thought I'd throw a note to you.. I notice that if I do a configure on fedora7 as a user I get the following... checking If XenD UNIX socket /var/run/xend/xmlrpc.sock is accessible... no Which works when you do a configure as root. Not sure what your using that for so not sure if it's a problem.. Mark

[Libvir] Storage manager initial requirements and thoughts
by Hugh Brock 15 Jun '07

15 Jun '07

Hi all. At the Red Hat virtualization team meeting last week we spent some time talking about the problem of remote storage management, which is a requirement for at the very least creating remote guests. Remote storage management also delivers a lot of benefits for managing guest storage, provisioning, and a host of other issues. Note that we don't (I think) believe that storage management should be part of libvirt. However we might want to be able to grab storage information with libvirt when creating a guest, for example. Here's the tentative requirements we came up with, along with several questions that came up. We have two important use cases for remote storage management: --Create a new guest against an existing physical device --Create a new guest against a file on an existing physical device (SELinux context must match up on both) Requirements: 2 key requirements: enumerate devices, create files * Enumerate devices (unallocated disks) * storage pool * Unallocated space * Allocated volumes -- free -- in use * Read only / Read-write * Host availability * Volume -- Global unique name -- Local device name -- Usage -- Mounted locally -- Assigned to guest read only shared exclusive -- Inactive guest * Create a backing store for a guest * need to know what storage is available * Can be plain file * Can be a physical partition (local scsi/IDE, SAN) * Can be a logical volume * Can be network - iscsi/nbd Cases: Physical device --> create partitions Volume group --> create logical volumes Directory --> create files Todos: Investigate gparted, one of the partition management tools we already have (apis? remote accessibility?) (I believe Jim Meyering volunteered to take a look at this?) Identify what other scenarios we need to address. Please comment; I'm hoping we can get these into a more definite form sooner rather than later. -- Red Hat Virtualization Group http://redhat.com/virtualization Hugh Brock | virt-manager http://virt-manager.org hbrock(a)redhat.com | virtualization library http://libvirt.org

[Libvir] [PATCH] setvcpus message
by Mark Johnson 15 Jun '07

15 Jun '07

This patch is probably not correct. I wasn't sure how to handle I18N in libvirt. Had a request to add an error message for setvcpus <domain> 0. This patch prints an error message for that case. Mark

[Libvir] Solaris patches applied
by Richard W.M. Jones 15 Jun '07

15 Jun '07

I applied the easy ones: * src/internal.h, src/virsh.c: Replace _N with N_ so that Solaris builds work (Mark Johnson). * src/virsh.c: Add a couple of missing error messages (Mark Johnson). * python/types.c: Fix NULL pointer deref on DEBUG build (Mark Johnson). * src/virsh.c: Spelling fix (Mark Johnson). I can't test if it works on Solaris, but it still builds on Linux. Now to look at the last patch you sent ... Thanks for your contribution to libvirt.

[Libvir] [PATCH] Spelling fix
by Mark Johnson 15 Jun '07

15 Jun '07

Hi all, This is the first of 10 or 11 patches I'll be submitting which gets libvirt compiling/working on a Solaris dom0. Also some minor generic bug fixing.. Sorry it took me so long from the Xen Summit.. Starting with a very simple one. :-) As I test them on the cvs tree on Fedora, I'll submit them.. So they'll trickle in over the next couple of days. A couple of them will probably require some discussion and changes. I'm applying the patches with the following # patch -t -s -p1 -i ../patches/spelling on todays CVS gate and tested on a fedora 7 dom0 (LD_PRELOAD=src/.libs/libvirt.so src/.libs/virsh) Thanks, Mark

[Libvir] no vfb for paravirt guest on RHEL 5 and strange args
by Glen Deem 13 Jun '07

13 Jun '07

Hi all, I'm creating a fairy simple paravirt machine under RHEL 5 (Xen 3.0.3, pygrub 0.6). A machine gets created but I see two problems: 1. no graphics console gets enabled (so RedHat VMM does not open it) so I cannot connect to it with vncviewer (am I naive to use vfb fpr a paravirt domU? - libvirt uses it, right?); 2. when I check what config has been used to create the domain (in /var/log/xen/xend.log) I see arguments ("args" or "extra") picked up from a virtual machine created a while age, my present "extra" parameter is ignored. I did regenerate xenstored/tdb and rebooted, still those args appear, drives my nuts :-). I'm actually after the graphics console, but I think both problems are related. Could anybody advise why I get no proper vfb setup (I'd expect a vnc-port vaue appearing in the xen store when it setup properly) and why I get those old args? Thanks in advance, Deem P.S. xm config ============ name = "para-2" memory = "256" disk = [ 'file:/var/lib/para-2.img,hda,w' ] vif = [ 'bridge=xenbr0' ] vfb = ['type=vnc, vncunused=1'] bootloader='/usr/bin/pygrub' vcpus=1 on_reboot = 'restart' on_crash = 'restart' extra = 'ignored' from /var/log/xen/xend.log: ================== [2007-06-12 17:13:56 xend.XendDomainInfo 5445] DEBUG (XendDomainInfo:940) XendDomainInfo.handleShutdownWatch [2007-06-12 17:41:57 xend.XendDomainInfo 5445] DEBUG (XendDomainInfo:190) XendDomainInfo.create(['vm', ['name', 'para-2'], ['memory', '256'], ['on_reboot', 'restart'], ['on_crash', 'restart'], ['vcpus', 1], ['bootloader', '/usr/bin/pygrub'], ['image', ['linux', ['ramdisk', '/var/lib/xen/initrd.NMeE1x'], ['kernel', '/var/lib/xen/vmlinuz.7QoaTW'], ['args', 'nosplash quiet rw acpi=on XXHOST=localhost.localdomain XXLDAP=127.0.0.1 resume2=swap:/dev/mapper/XxxxxxVG-swap vga=791 root=/dev/XxxxxxxVG/root']]], ['device', ['vbd', ['uname', 'file:/var/lib/para-2.img'], ['dev', 'hda'], ['mode', 'w']]], ['device', ['vif', ['bridge', 'xenbr0']]], ['device', ['vkbd']], ['device', ['vfb', ['vncunused', '1'], ['type', 'vnc'], ['display', ':0.0'], ['xauthority', '/root/.xauthfLRNzX']]]])

[Libvir] New vs old-style hypercalls
by Richard W.M. Jones 12 Jun '07

12 Jun '07

In xen_internal.c we've got code which claims to sniff out whether we are using new-style hypercall ioctls or old-style hypercall ioctls. hc.op = __HYPERVISOR_xen_version; hc.arg[0] = (unsigned long) XENVER_version; hc.arg[1] = 0; cmd = IOCTL_PRIVCMD_HYPERCALL; ret = ioctl(fd, cmd, (unsigned long) &hc); if ((ret != -1) && (ret != 0)) { #ifdef DEBUG fprintf(stderr, "Using new hypervisor call: %X\n", ret); #endif hv_version = ret; xen_ioctl_hypercall_cmd = cmd; goto detect_v2; } /* * check if the old hypercall are actually working */ v0_hc.op = __HYPERVISOR_xen_version; v0_hc.arg[0] = (unsigned long) XENVER_version; v0_hc.arg[1] = 0; cmd = _IOC(_IOC_NONE, 'P', 0, sizeof(v0_hypercall_t)); ret = ioctl(fd, cmd, (unsigned long) &v0_hc); But on 64 bit platforms (not 32 bit) cmd will be identical, so we'll just be trying the same ioctl twice. From <xen/linux/privcmd.h>: typedef struct privcmd_hypercall { __u64 op; __u64 arg[5]; } privcmd_hypercall_t; #define IOCTL_PRIVCMD_HYPERCALL \ _IOC(_IOC_NONE, 'P', 0, sizeof(privcmd_hypercall_t)) From src/xen_internal.c: typedef struct v0_hypercall_struct { unsigned long op; unsigned long arg[5]; } v0_hypercall_t; cmd = _IOC(_IOC_NONE, 'P', 0, sizeof(v0_hypercall_t)); On 64 bit platforms, both structures will be the same size.

[Libvir] [PATCH] add bootloader_args to libvirt xml to support bootloaders (like pypxeboot for example) that require arguments
by Hugh Brock 07 Jun '07

07 Jun '07

This patch extends libvirt's XML to include a paramater Xen already supports in sexpr, "bootloader_args." The bootloader_args parameter lets you pass arguments -- "mac=aa:12:34:56:78:90" for example -- to a bootloader program that xend invokes when it starts a guest. One such program, pypxeboot, uses the mac= argument to communicate with a dhcp server and retrieve the pxeboot kernel and initrd for a paravirt guest. The patch includes new tests for the bootloader_args XML and sexpr, which pass. Note that for the head of current libvirt, the virsh tests do not pass and virsh will not connect to the xen hypervisor. I don't know if this is my own build environment or some other issue. However the failure is the same with or without this patch, so I am submitting it anyway. Please let me know what you think... --Hugh -- Red Hat Virtualization Group http://redhat.com/virtualization Hugh Brock | virt-manager http://virt-manager.org hbrock(a)redhat.com | virtualization library http://libvirt.org
