Hello, I would like to ask what I am doing wrong and what is the best approach to resolve this situation:
First of all I start virtual machine by virDomainCreateXML. In my application I use libvncclient library that sends mouse events to this running domain. I had some troubles with coordinates of mouse cursor but all problem was solved when I added <input type='tablet' bus='usb'/> to xml configuration. So now I have a running domain and I want to create snapshot and then after some operations I want to restore this snapshot. I use virDomainSave and virDomainRestore that work fine. The only problem is, that after creating and restoring snapshot I have the same problem with coordinates of mouse. I need to create and restore snapshot also with <input type='tablet' bus= 'usb'/> somewhere specified. I also tried methods virDomainSaveFlags with xml configuration string(see below) as parameter *dxml, but method fails with: libvir: Domain Config error : XML error: domainsnapshot.Unable to create snapshot. What should I add to xml configuration? I look at http://libvirt.org/ formatsnapshot.html on example but I dont know what paths I should use in my program. I dont understand much snapshots and similar stuff so could you give me example how could I edit my xml configuration? Or what I should do to make virDomainSave and virDomainRestore work? xml configuration: <domain type='kvm'> <name>Name</name> <uuid>c7a5fdbd-cdaf-9455-926a-d65c16db1810</uuid> <memory unit='KiB'>524288</memory> <currentMemory unit='KiB'>524288</currentMemory> <vcpu>2</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <devices> <input type='tablet' bus='usb'/> <emulator>/usr/bin/qemu-system-x86_64</emulator> <disk type='file' device='disk'> <source file='/home/lukas/Desktop/Image.img'/> <target dev='hda'/> </disk> <interface type='network'> <source network='default'/> </interface> <graphics type='vnc' port='5901'> <listen type='address' address='127.0.0.1'/> </graphics> </devices> </domain>
