Hello, I'm trying to get memory usage statistic inside a guest machine using virDomainMemoryStats function at libvirt. According to http://libvirt.org/html/libvirt-libvirt.html#virDomainMemoryStatTags the structure could have a lot of useful memory statistic but the amount of parameters depends on the hypervisor and the driver. However using KVM I'm able to get

Hello, I've been trying to clone one disk image (LVM) to another using virt-resize. Unfortunately I get the following error: # virt-resize /dev/vm/vm6 /dev/vm/vm7 supermin helper [00004ms] finished creating kernel supermin helper [00251ms] finished mke2fs <domain type='kvm'> supermin helper [00252ms] visiting /usr/lib64/guestfs/supermin.d supermin helper [00252ms] visiting

Hello, A collecting period should be set to get domain memory stats (virDomainSetMemoryStatsPeriod function or virsh dommemstat --period from command line). Is there a way to set this period automatically using XML config or any other way?
