Hi! As mentioned in an earlier mail I have installed KVM on a logical volume like this (CentOS 7): [#] lvcreate -L 300G -n lv_vm1 VolGroup [#] virt-install --name=vm1.mydomain.com \ --disk path=/dev/VolGroup/lv_vm1 \ --ram=8192 --os-type=linux --os-variant=rhel7 \ --vcpus=8 --check-cpu \ --network bridge:br0 --nographics \ --location=/usr/local/src/linux_isos/CENTOS7/CentOS-7.0-1406-x86_64-Minimal.iso \ --extra-args 'ks=http://www.mydomain.com/anaconda-ks.cfg ksdevice=eth0 \ ip=192.168.19.2 netmask=255.255.255.192 dns=8.8.8.8 gateway=192.168.19.1 console=ttyS0,115200n8 serial’ I would like to run fstrim from within the VM client (I have fstrim working on the VM host machine). Running fstrim from within the VM gives me errors like this: "fstrim: /usr: FITRIM ioctl failed: Operation not supported" Is it possible to run fstrim on the VM client with the setup described above? Thanks for any feedback!
