Description of problem: If I run vm under PPC cluster, with memory size not multiplier of 256(1000MB) I receive qemu error under engine log "2015-09-08 13:08:06,147 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-36) [] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM test is down with error. Exit message: internal error: early end of file from monitor: possible problem: 2015-09-08T10:07:41.489898Z qemu-kvm: Can't support memory configuration where RAM size 0x3e800000 or maxmem size 0x3e800000 isn't aligned to 256 MB." Version-Release number of selected component (if applicable): rhevm-3.6.0-0.13.master.el6.noarch vdsm-4.17.5-1.el7ev.noarch qemu-kvm-rhev-2.3.0-22.el7.ppc64le How reproducible: Always Steps to Reproduce: 1. Create vm with 1000MB on ppc hosts 2. Run vm 3. Actual results: Create action success, but vm failed to run Expected results: If it qemu limitation, I want to validate memory size on create(update) action and give to user message, that under PPC cluster he can only have vms with memory size equal to multiplier of 256 Additional info: I do not sure what a reason why we have such limitation from qemu for ppc, maybe it worth to check it will qemu dev team
Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release.
Moving from 4.0 alpha to 4.0 beta since 4.0 alpha has been already released and bug is not ON_QA.
Verified with rhevm- 4.0.2.3-0.1.el7ev with hosts: vdsm-4.18.10-1.el7ev kernel version: 3.10.0 - 327.30.1.el7.ppc64le Manufacturer: IBM Family: PowerNV Product Name: IBM Power System S824 Version: PowerNV 8286-42A CPU Model Name: POWER8E (raw), altivec supported Cluster set to IBM POWER8 cluster. Verified that trying to create/edit vm with 10000MB failed and the proper message appear when hovering above the memory field. When editing/creating with a value which is multiplier of 256 action succeeds.
