[libvirt] Save and restore with KVM!
by Erkan Unal 06 Jul '09

06 Jul '09

Hi, First of all, I want to ask: is there a libvirt user mailing list? I generally see people exchanging ideas on development of libvirt in this mailing list. So feel free to direct me to the right place if this is not the main mailing list for these kind of questions. I am having problems with save and restore commands in virsh when I try to save and restore KVM virtual machines. After I initiate restore operation, instead of starting where I left during the save operation, it is restarting the VM. Therefore, I need to ask what should I check for these operations to execute correctly? What kind of vm disk types: qcow or vmdk? Which versions of qemu, kvm and libvirt combinations? currently I have libvirt 0.6.5, qemu 0.9.1, kvm-82 on fedora core 8 with kernel version of 2.6.26.8. Thanks, Erkan Unal

I see that the mips machines are separated into 'mips' and 'mipsel'. I don't know anything about the endian-ness of the various machines (aside from versatilepb, which is little), so I just left them all in the generic qemu_arch_info.arch="arm" table entry. > Daniel Cheers, C.J. > [1] the server seems down I got an HTTP request timeout. hurm...

[libvirt] vTPM support in libvirt
by Andreas Sommer 02 Jul '09

02 Jul '09

I'm wondering if there will be vTPM support in libvirt in the near future?! Xen does support it already with the configuration "vtpm = ['instance=1,backend=0']", for example. So it would be great if the libvirt XML format supported it, too... For example like this: <devices> <vtpm instance="1" backend="xxx" /> </devices> Both attributes are optional. The backend attribute is a VM ID (on Xen, only zero for dom0 is supported) and could be implemented as a UUID?! What do you think? Are there any efforts to introducing that? Cheers Andreas
