[libvirt] Question about more finer access control permission on libvirt
by Atsushi SAKAI 16 May '08

16 May '08

Hi, Dan I have a question of libvirt with Polkit. Currently, the libvirt w/ Polkit has 2 access control permissions. (Read Only and Read Write) Have you planned to expand the access control more finer? In my use case, Policy should define by domain, operation, operator. Of course, operator is already considered on current libvirt w/ Polkit. So at this point, it needs to add domain and operation policy. The use case is for many(about 100 or more) domain operation. I just want to know how to minimize granting access control permission of each user on libvirt in future. Any comment appreciated. Thanks Atsushi SAKAI

[libvirt] [PATCH] start using c-ctype functions
by Jim Meyering 16 May '08

>From db0ed598dfc045f3937a3629a432d2d703449f50 Mon Sep 17 00:00:00 2001 From: Jim Meyering <meyering(a)redhat.com> Date: Wed, 14 May 2008 23:06:15 +0200 Subject: [PATCH] start using c-ctype functions Up to now, we've been avoiding ctype functions like isspace, isdigit, etc. Now that we have the c-ctype functions, we can start using them to make the code more readable with changes like these: - /* This may not work on EBCDIC. */ - if ((*p >= 'a' && *p <= 'z') || - (*p >= 'A' && *p <= 'Z') || - (*p >= '0' && *p <= '9')) + if (c_isalnum(*p)) - while ((*cur >= '0') && (*cur <= '9')) { + while (c_isdigit(*cur)) { Also, some macros in conf.c used names that conflicted with standard meaning of "BLANK" and "SPACE", so I've adjusted them to be in line with the definition of e.g., isblank. In addition, I've wrapped those statement macros with do {...} while (0), so that we can't forget the ";" after a use. There was one like that already (fixed below).

[libvirt] [ANNOUNCE] virt-df 2.1.0 - a 'df' tool for virtual guests
by Richard W.M. Jones 16 May '08

16 May '08

I'm pleased to announce the most recent release of virt-df (2.1.0). Virt-df is 'df' for virtual guests. Run the program on the host / dom0 to display disk space used and available on all partitions on all guests. You don't need to run any sort of program/agent within the guest. Home page: http://et.redhat.com/~rjones/virt-df/ Source/binaries: http://et.redhat.com/~rjones/virt-df/files/ Developer repository: http://hg.et.redhat.com/virt/applications/virt-df--devel This version supports most common filesystems and partitioning schemes, including: - Linux ext2/3 - DOS FAT32 - Windows NTFS - Linux LVM2 (volume groups and logical volumes) - Primary and extended disk partitions - Linux swap - Linux suspend partition You can run it in your host / dom0 to display guest filesystems: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap You can also run it on general disk images, or disk devices: # virt-df -t /dev/sda Filesystem 1K-blocks Used Available Type /dev/sda:hda1 25599996 11309448 14290552 Windows NTFS /dev/sda:hda2 992016 93772 898244 Linux ext2/3 /dev/sda:F9VG/F9Root 23316072 7818164 15497908 Linux ext2/3 /dev/sda:F9VG/F9Swap 1015808 Linux swap /dev/sda:RHEL51VG/RHEL51Root 22382184 7796640 14585544 Linux ext2/3 /dev/sda:RHEL51VG/RHEL51Swap 2031616 Linux swap /dev/sda:VolGroup/FAT32Test 916736 4 914676 DOS/Windows You can write the output to a CSV file (use --csv option) in order to import the data easily into spreadsheets and databases. Included also is an experimental command line tool called 'diskzip' which intelligently compresses disk images by leaving out the bits which aren't actually used in the filesystems / partitions / volume groups contained within.

[libvirt] [PATCH] Extract kvm version from qemu-kvm
by Cole Robinson 16 May '08

The patch below provides a way to check the kvm version by parsing the output of qemu-kvm, similar to how the qemu version is parsed. The qemu-kvm binary help info starts with the line: "QEMU PC emulator version major.minor.micro (KVM-ver)" The patch is kind of ugly, with renamed functions and code movement. The gist of it is: - Moved the general run-a-command-and-grab-output into its own function qemudExtractCommandOutput - Created qemudExtract{Qemu,KVM}VersionInfo which call the above function and scrape the output - Use qemudExtractVersion to find the default binaries and call the *VersionInfo functions If there is a parsing error, or kvm support isn't found, the new kvmVersion in the qemud_driver struct is just set to zero. I also added a call to fill in the qemu and kvm versions on driver init. The patch also fills in the previously discussed max vcpus piece, which is dependent on the kvm version. Any comments appreciated.

[libvirt] [RFC] Publishing utilisation on mDNS
by Stefan de Konink 16 May '08

16 May '08

After playing around with Avahi, I have now a server that is able to query all hosts on the network and their VMs, I think it would be interesting to publish utilisation statistics in the Txt record of the service. Of course one could login to a host and fetch the info, but I think it would be (managementwise) interesting if the hosts would announce this information. The implication for libvirtd would be a thread that updates lets say, per minute the avarage cpu load / free memory. I might even go further and publish all resource statistics over mDNS. Maybe people have ideas about this too, securitywise i'm not really interested in the implications since I'm publishing it on a management LAN. Stefan

[libvirt] PATCH: Support bootloaders in QEMU driver
by Daniel P. Berrange 16 May '08

16 May '08

The QEMU driver supports booting Xen guests via the Xenner hypervisor. For such paravirtualized guests there is no regular BIOS, so the bootloader has to be run on the host. Xenner defaults to pygrub, but since libvirt has a generic syntax for bootloaders, we should use it. So this patch adds support for the <bootloader> syntax in the QEMU drive, and passes this to Xenner via the -bootloader arg. The patch is overly large, because when we have a bootloader we need to skip the kernel/initrd/cmdline/boot elements & thus caused alot of intrusive code re-indentation . b/tests/qemuxml2argvdata/qemuxml2argv-bootloader.args | 1 b/tests/qemuxml2argvdata/qemuxml2argv-bootloader.xml | 23 + src/qemu_conf.c | 318 +++++++++--------- src/qemu_conf.h | 1 tests/qemuxml2argvtest.c | 1 tests/qemuxml2xmltest.c | 1 6 files changed, 200 insertions(+), 145 deletions(-) Dan. diff -r f6b693192cb2 src/qemu_conf.c --- a/src/qemu_conf.c Mon May 12 09:51:07 2008 -0400 +++ b/src/qemu_conf.c Mon May 12 10:16:21 2008 -0400 @@ -1702,22 +1702,37 @@ xmlXPathFreeObject(obj);

[libvirt] PATCH: Allow xen bus type for disks in QEMU driver
by Daniel P. Berrange 16 May '08

16 May '08

With the recent work to support -drive arg, the QEMU driver now supports many types of bus for disks attached to VMs - ide, scsi, virtio. This patches adds another type 'xen' for the Xen blkfront driver. b/tests/qemuxml2argvdata/qemuxml2argv-disk-xenvbd.args | 1 b/tests/qemuxml2argvdata/qemuxml2argv-disk-xenvbd.xml | 35 +++++++++++++++++ src/qemu_conf.c | 8 ++- src/qemu_conf.h | 1 src/util.c | 24 ++++------- tests/qemuxml2xmltest.c | 1 6 files changed, 53 insertions(+), 17 deletions(-) Dan. diff -r f6b47c9986b9 src/qemu_conf.c --- a/src/qemu_conf.c Sat May 10 12:57:20 2008 -0400 +++ b/src/qemu_conf.c Sat May 10 12:57:46 2008 -0400 @@ -667,7 +667,8 @@ if ((!device || STREQ((const char *)device, "disk")) && !STRPREFIX((const char *)target, "hd") && !STRPREFIX((const char *)target, "sd") && - !STRPREFIX((const char *)target, "vd")) { + !STRPREFIX((const char *)target, "vd") && + !STRPREFIX((const char *)target, "xvd")) { qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, _("Invalid harddisk device name: %s"), target); goto error; @@ -707,6 +708,8 @@ disk->bus = QEMUD_DISK_BUS_SCSI; else if (STREQ((const char *)bus, "virtio")) disk->bus = QEMUD_DISK_BUS_VIRTIO; + else if (STREQ((const char *)bus, "xen")) + disk->bus = QEMUD_DISK_BUS_XEN; else { qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, _("Invalid bus type: %s"), bus); @@ -1435,7 +1438,8 @@ const char *busnames[] = { "ide", (qemuIF ?

[libvirt] PATCH: Allow Xen bus type for input devices in QEMU driver
by Daniel P. Berrange 16 May '08

16 May '08

The Xenner virtual machine supportes a bus type of 'xen' for input devices, corresponding to the paravirtualized mouse device. QEMU currently rejects any bus type which isn't ps2 or usb. This patch makes it allow 'xen' as a valid bus type for Xenner guests. b/tests/qemuxml2argvdata/qemuxml2argv-input-xen.args | 1 b/tests/qemuxml2argvdata/qemuxml2argv-input-xen.xml | 24 ++++++ src/qemu_conf.c | 72 ++++++++++++------- src/qemu_conf.h | 3 src/qemu_driver.c | 2 tests/qemuxml2argvtest.c | 2 tests/qemuxml2xmltest.c | 1 7 files changed, 78 insertions(+), 27 deletions(-) Dan. diff -r f00771a60241 src/qemu_conf.c --- a/src/qemu_conf.c Sat May 10 12:57:47 2008 -0400 +++ b/src/qemu_conf.c Sat May 10 13:00:01 2008 -0400 @@ -1365,6 +1365,7 @@ /* Parse the XML definition for a network interface */ static int qemudParseInputXML(virConnectPtr conn, + struct qemud_vm_def *vm, struct qemud_vm_input_def *input, xmlNodePtr node) { xmlChar *type = NULL; @@ -1391,26 +1392,46 @@ } if (bus) { - if (STREQ((const char*)bus, "ps2")) { /* Only allow mouse */ - if (input->type == QEMU_INPUT_TYPE_TABLET) { - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, - _("ps2 bus does not support %s input device"), - (const char*)type); - goto error; - } - input->bus = QEMU_INPUT_BUS_PS2; - } else if (STREQ((const char *)bus, "usb")) { /* Allow mouse & keyboard */ - input->bus = QEMU_INPUT_BUS_USB; - } else { - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, - _("unsupported input bus %s"), (const char*)bus); - goto error; - } - } else { - if (input->type == QEMU_INPUT_TYPE_MOUSE) - input->bus = QEMU_INPUT_BUS_PS2; - else - input->bus = QEMU_INPUT_BUS_USB; + if (STREQ(vm->os.type, "hvm")) { + if (STREQ((const char*)bus, "ps2")) { /* Only allow mouse */ + if (input->type == QEMU_INPUT_TYPE_TABLET) { + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("ps2 bus does not support %s input device"), + (const char*)type); + goto error; + } + input->bus = QEMU_INPUT_BUS_PS2; + } else if (STREQ((const char *)bus, "usb")) { /* Allow mouse & tablet */ + input->bus = QEMU_INPUT_BUS_USB; + } else { + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("unsupported input bus %s"), (const char*)bus); + goto error; + } + } else { + if (STREQ((const char *)bus, "xen")) { /* Allow mouse only */ + input->bus = QEMU_INPUT_BUS_XEN; + if (input->type == QEMU_INPUT_TYPE_TABLET) { + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("xen bus does not support %s input device"), + (const char*)type); + goto error; + } + } else { + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("unsupported input bus %s"), (const char*)bus); + goto error; + } + } + } else { + if (!strcmp(vm->os.type, "hvm")) { + if (input->type == QEMU_INPUT_TYPE_MOUSE) + input->bus = QEMU_INPUT_BUS_PS2; + else + input->bus = QEMU_INPUT_BUS_USB; + } else { + input->bus = QEMU_INPUT_BUS_XEN; + } } xmlFree(type); @@ -1998,7 +2019,7 @@ "%s", _("failed to allocate space for input string")); goto error; } - if (qemudParseInputXML(conn, input, obj->nodesetval->nodeTab[i]) < 0) { + if (qemudParseInputXML(conn, def, input, obj->nodesetval->nodeTab[i]) < 0) { free(input); goto error; } @@ -2852,7 +2873,7 @@ struct qemud_vm_device_def * qemudParseVMDeviceDef(virConnectPtr conn, - struct qemud_driver *driver ATTRIBUTE_UNUSED, + struct qemud_vm_def *def, const char *xmlStr) { xmlDocPtr xml; @@ -2880,7 +2901,7 @@ qemudParseInterfaceXML(conn, &(dev->data.net) node); } else if (xmlStrEqual(node->name, BAD_CAST "input")) { dev->type = QEMUD_DEVICE_DISK; - qemudParseInputXML(conn, &(dev->data.input), node); + qemudParseInputXML(conn, def, &(dev->data.input), node); } else if (xmlStrEqual(node->name, BAD_CAST "sound")) { dev->type = QEMUD_DEVICE_SOUND; qemudParseSoundXML(conn, &(dev->data.sound), node); @@ -3950,14 +3971,15 @@ input = def->inputs; while (input) { - if (input->bus != QEMU_INPUT_BUS_PS2) + if (input->bus == QEMU_INPUT_BUS_USB) virBufferVSprintf(&buf, " <input type='%s' bus='usb'/>\n", input->type == QEMU_INPUT_TYPE_MOUSE ?
