Hi All, Can anybody please help me in the issue? Regards, Srikanth. From: Kumar L Srikanth-B22348 Sent: Wednesday, April 28, 2010 4:47 PM To: 'Daniel P. Berrange' Subject: FW: Creating multiple network interfaces in libvirt Domain. Also, can you please let me know, how can I create multiple interfaces in the guest domain using Domain XML? Regards, Srikanth. From: Kumar L Srikanth-B22348 Sent: Wednesday, April 28, 2010 2:26 PM To: 'berrange(a)redhat.com' Cc: 'libvir-list(a)redhat.com' Subject: Creating multiple network interfaces in libvirt Domain. Hi, I want to create a Domain with two interfaces. I am using LXC hypervisor in the libvirt. My domain XML is shown below: <domain type='lxc' id='1'> <name>srikanth_vm2</name> <memory>500000</memory> <os> <type>exe</type> <init>/bin/sh</init> </os> <vcpu>1</vcpu> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>destroy</on_crash> <devices> <emulator>/usr/libexec/libvirt_lxc</emulator> <filesystem type='mount'> <source dir='/root/lxc/fedora1'/> <target dir='/'/> </filesystem> <interface type='network'> <source network='default'/> </interface> <interface type='network'> <source network='default'/> </interface> <console type='pty' /> </devices> </domain> I am able to define the Domain. But, I am not able to start the Domain. While starting the domain, I am getting the following error: error: Failed to start domain srikanth_vm2 error: internal error Failed to create veth device pair: 512 Can you please let me know where I am going wrong? Regards, Srikanth.

[libvirt] [PATCH] cygwin/mingw: Fix version script handling
by Matthias Bolte 28 Apr '10

28 Apr '10

Let configure detect ld instead of hardcoding /usr/bin/ld, because MinGW may have ld in /bin. Only use a .def file to export symbols on MinGW.

[libvirt] new NULL-dereference in qemu_driver.c
by Jim Meyering 28 Apr '10

28 Apr '10

I ran clang on the very latest and it spotted this problem: >From qemu_driver.c, around line 11100, else { /* qemu is a little funny with running guests and the restoration * of snapshots. If the snapshot was taken online, * then after a "loadvm" monitor command, the VM is set running * again. If the snapshot was taken offline, then after a "loadvm" * monitor command the VM is left paused. Unpausing it leads to * the memory state *before* the loadvm with the disk *after* the * loadvm, which obviously is bound to corrupt something. * Therefore we destroy the domain and set it to "off" in this case. */ if (virDomainObjIsActive(vm)) { qemudShutdownVMDaemon(driver, vm); event = virDomainEventNewFromObj(vm, VIR_DOMAIN_EVENT_STOPPED, VIR_DOMAIN_EVENT_STOPPED_FROM_SNAPSHOT); if (!vm->persistent) { if (qemuDomainObjEndJob(vm) > 0) virDomainRemoveInactive(&driver->domains, vm); vm = NULL; } } if (qemuDomainSnapshotSetActive(vm, driver->snapshotDir) < 0) goto endjob; } vm->state = snap->def->state; ret = 0; endjob: if (vm && qemuDomainObjEndJob(vm) == 0) vm = NULL; Note how "vm" is set to NULL. Then, it can be dereferenced both via qemuDomainSnapshotSetActive and via the vm->state = ... assignment.

[libvirt] [PATCH 0/3] Add dnsmasq module (v2)
by Satoru SATOH 28 Apr '10

28 Apr '10

The following series of patches is a prototype implementation of dnsmasq module. It implements an idea to save dhcp hosts' macaddr vs. ipaddr mappings to static file and make dnsmasq loading it with "--dhcp-hostsfile" option, originally suggested by Dan-san, and can address the problem that too many "--dhcp-host" args hitting ARG_MAX limit I reported last year [1]. This is a updated version reflecting some advices from Jim-san [2] and Eric-san [3].

[libvirt] [PATCH 00/10]: Add arbitrary qemu command-line and monitor commands
by Chris Lalancette 28 Apr '10

28 Apr '10

As we discussed previously, here is the patch series to add the ability to specify arbitrary qemu command-line parameters and environment variables, and also give arbitrary monitor commands to a guest. Because these extra arguments have a good shot at confusing libvirt, the use of them is not supported, but left available for advanced users and developers. They are also in a separate library and have a separate on-the-wire protocol. There is one bug left that I have not yet been able to fix. Because of the complicated way that virsh parses command-line arguments, it is not possible to pass through spaces and quotes when using the qemu-monitor-command. Unfortunately, the qemu monitor commands (and in particular when using QMP) depend heavily on quoting and spacing, so using virsh to send through command-lines is difficult. I'll have to think about how to better resolve this issue, but it should not hold up the rest of the series. Thanks to Dan Berrange for his review already, and to DV for the Relax NG schema changes.
