...l file for a vm, libvirt appears to be > removing them. Please email libvirt-users at redhat.com for questions about libvirt in the future. This is a question about libvirt domain XML. The documentation is here: http://libvirt.org/formatdomain.html#elementsDisks The attribute is called "error_policy". The documentation says: The optional error_policy attribute controls how the hypervisor will behave on a disk read or write error, possible values are "stop", "report", "ignore", and "enospace".Since 0.8.0, "report" since 0.9.7 The...

...however it does not appear to be working and I wanted to see if I was doing something wrong. I define the alias like so (using 'virsh edit'): <disk type='file' device='disk'> <driver name='qemu' type='qcow2' cache='writeback' error_policy='stop' discard='unmap'/> ...truncated... <alias name='ua-test'/> </disk> However, when I then 'virsh dumpxml {guest}', the alias is not there. There is no error given after my edits are made and saved. It just seems that libvirt...

...power to access its image file is the max or min? if any other power this process(domain) has?how much? i want to know the exact power a qemu-kvm process has besides access its image file ,other kinds of files,dirs etc. my test case: after start a guestVM(its disk xml ,cache='none' error_policy='stop'), make some modification on its files and save them. then go to hypervisor, modify the MCS of guestVM's image file. 1.i can read those files(cache=none)?it should not be so. why? 2.then modify files and save, the guestVM hang, it is paused on UI. this is right qeum process c...

Hello everyone, Current host build is RHEL 6.2, soon to be upgrading. I'm in the process of mapping out a KVM/RHEV topology. I have questions about the landscape of storage pools and the instantiation of specific scsi_host IDs using virsh nodedev-create and some magic XML definitions. I'm grouping these questions together because the answer to one may impact the other. High-level

Hello, what happens when an instance writes data with 0% available physical disk space, on QCOW2 images for instance, apart from destruction and unpredictability? I'm aware that monitoring is mandatory in production environments, but are there other known industry tricks to deal with this? Soft/hard limit settings, autopause/stop, or does KVM react in doing force shut down the VM in
