About the vm memory limit
by Tommy Sway 24 Sep '21

24 Sep '21

I would like to ask if there is any limit on the memory size of virtual machines, or performance curve or something like that? As long as there is memory on the physical machine, the more virtual machines the better? In our usage scenario, there are many virtual machines with databases, and their memory varies greatly. For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed. I want to know what is the best use of memory for a virtual machine, since the virtual machine is just a QEMU emulation process on a physical machine, and I worry that it is not using as much memory as a physical machine. Understand this so that we can develop guidelines for optimal memory usage scenarios for virtual machines. Thank you!

about the power management of the hosts
by Tommy Sway 23 Sep '21

23 Sep '21

Everybody, hi: I would like to ask, after the configuration of power management on the host, under what circumstances will work? That is, when does the engine send a request to the IPMI module to restart the power supply? Is it necessary to configure power management modules in the production environment? Are there any risks? Thanks!

Sparse VMs from Templates - Storage issues
by Shantur Rathore 23 Sep '21

23 Sep '21

Hi all, I have a setup as detailed below - iSCSI Storage Domain - Template with Thin QCOW2 disk - Multiple VMs from Template with Thin disk oVirt Node 4.4.4 When the VMs boots up it downloads some data to it and that leads to increase in volume size. I see that every few seconds the VM gets paused with "VM X has been paused due to no Storage space error." and then after few seconds "VM X has recovered from paused back to up" Sometimes after a many pause and recovery the VM dies with "VM X is down with error. Exit message: Lost connection with qemu process." and I have to restart the VMs. My questions. 1. How to work around this dying VM? 2. Is there a way to use sparse disks without VM being paused again and again? Thanks in advance. Shantur

about the vm disk type
by Tommy Sway 23 Sep '21

23 Sep '21

When I create the VM's image disk, I am not asked to select the following type of disk. What is the default value ? Thanks. QCOW2 Formatted Virtual Machine Storage QCOW2 is a storage format for virtual disks. QCOW stands for QEMU copy-on-write. The QCOW2 format decouples the physical storage layer from the virtual layer by adding a mapping between logical and physical blocks. Each logical block is mapped to its physical offset, which enables storage over-commitment and virtual machine snapshots, where each QCOW volume only represents changes made to an underlying virtual disk. The initial mapping points all logical blocks to the offsets in the backing file or volume. When a virtual machine writes data to a QCOW2 volume after a snapshot, the relevant block is read from the backing volume, modified with the new information and written into a new snapshot QCOW2 volume. Then the map is updated to point to the new place. Raw The raw storage format has a performance advantage over QCOW2 in that no formatting is applied to virtual disks stored in the raw format. Virtual machine data operations on virtual disks stored in raw format require no additional work from hosts. When a virtual machine writes data to a given offset in its virtual disk, the I/O is written to the same offset on the backing file or logical volume. Raw format requires that the entire space of the defined image be preallocated unless using externally managed thin provisioned LUNs from a storage array.

why cannot set the power management proxy server ?
by Tommy Sway 23 Sep '21

23 Sep '21

I can use ipmitool to send commands from any KVM host to other hosts in the same cluster. However, an internal error is reported when CONFIGURING power proxy on engine. How can I locate the fault?

about the OVF_STORE and the xleases volume
by Tommy Sway 23 Sep '21

23 Sep '21

I wonder if the xleases volume mentioned here refers to ovf_store ? * A new xleases volume to support VM leases - this feature adds the ability to acquire a lease per virtual machine on shared storage without attaching the lease to a virtual machine disk. A VM lease offers two important capabilities: * Avoiding split-brain. * Starting a VM on another host if the original host becomes non-responsive, which improves the availability of HA VMs.

Frequent events seen like VM "vmname" is not responding
by manoj.sharma99765＠gmail.com 22 Sep '21

22 Sep '21

I am using oVirt Open Virtualization Manager Software Version:4.4.6.8-1.el8 and we have single node running on oVirt Node 4.4.6. We are facing slowness while using VM and also we face connection reset issue between VM and Target servers ( Nexus ) We are getting below logs in ovirt manager events VM "vmname" is not responding Getting this for all the running VMs . We checked resources and utilization of the node everything seems very normal. Could you please guide on how can we solve/debug further on this ?
