[libvirt] virsh capabilities, kvm with apic and toggle
When I run 'virsh capabilities' on a libvirt 0.6.4 system with qemu 0.10 and kvm-84, one of the results I get is: guest os_typehvm/os_type arch name='x86_64' wordsize64/wordsize emulator/usr/bin/qemu-system-x86_64/emulator machinepc/machine machineisapc/machine domain type='qemu' /domain domain type='kvm' emulator/usr/bin/kvm/emulator /domain /arch features acpi default='on' toggle='yes'/ apic default='on' toggle='no'/ /features /guest I'm wondering why the apic feature can't be toggled.

Now, while this is still a hacky way to solve this problem, would anyone be interested in seeing a patch that would either: 1) Allow one to append arbitrary command line arguments to the emulator, like: ... emulator/usr/bin/kvmemulator emulator_args-no-kvm-irqchip/emulator_args ... I don't like the name emulator_args much either, but just as an example. 2) Have an option in the XML file specifically for '-no-kvm-irqchip'; I'm not sure where it would go. Maybe under features, yet it isn't really a feature, more like lack of a feature ;) Suggestions welcome. I've been waiting to find some itch to scratch where I can contribute to libvirt code directly (instead of just doc patches), so this seems to fit the bill. -- Garry Dolley ARP Networks, Inc. | http://www.arpnetworks.com | (818) 206-0181 Data center, VPS, and IP Transit solutions Member Los Angeles County REACT, Unit 336 | WQGK336 Blog http://scie.nti.st -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

I've heard of folks having trouble doing live migration over NFS -- something with stronger concurrency guarantees (GFS, a shared iSCSI or FC mount [possibly with cLVM to partition it up], etc) is likely to be a safer bet. (Indeed, looking at the documented preferred environment for VMware's VMotion is probably a good guideline for anything that's going to be trusted with real production usage -- a separate bonded pair of NICs on each host, connected to a dedicated network for communication with the SAN hosting the backing store). A method I'm going to be trying out very shortly is using DRBD in dual-primary mode. DRBD will keep LVM volumes (block devices) for each VM in sync between two nodes. Upon migration, writes will cease on node A and when ready, begin on node B. You won't have concurrent writes, so it will be safe to use DRBD directly without a clustering FS on top (GFS, OCFS2, etc...). DRBD has scripts for Xen that take care of the details for you. Haven't seen the same for KVM/QEMU yet, but I imagine it would be pretty similar. -- Garry Dolley ARP Networks, Inc. | http://www.arpnetworks.com | (818) 206-0181 Data center, VPS, and IP Transit solutions Member Los Angeles County REACT, Unit 336 | WQGK336 Blog http://scie.nti.st -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list

I must ^C it again. If I do 'virsh list' again, it'll then show nothing (hangs like it does above). Any suggestions? Install the -debug packages for libvirt, and get a trace of all its threads under GDB, eg (gdb) thread apply all backtrace Also, capture traces of the client server, by setting LIBVIRT_DEBUG=1 before running each. I solved the problem, but thanks for this info. I'll use it next time. How do I attach gdb to a running process?

I want my users to only be able to connect to their own virtual machines via VNC. Is there any way to do so? The VNC authentication setup is currently being done per-host, so there is no way to define ACLs per-(user,vm) tuple as you describe. What about the VNC password? That's per-VM, isn't it? With KVM/QEMU, you can set a VNC password per VM. But I think it is either/or though; you can use VNC with passwords (no encryption), or use VNC with TLS, which is encrypted, but anyone with a valid certificate can connect (to any VM). Someone correct me if I'm wrong on that. -- Garry Dolley ARP Networks, Inc. | http://www.arpnetworks.com | (818) 206-0181 Data center, VPS, and IP Transit solutions Member Los Angeles County REACT, Unit 336 | WQGK336 Blog http://scie.nti.st -- Libvir-list mailing list Libvir-list@redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
