qemu: update domain live xml for virsh memtune with --live flag
virsh subcommand memtune forgot updating domain live xml
after setting cgroup value.
We decided not to rebase libvirt in RHEL 6.5 to avoid stability issues we faced in 6.4. This bug has already been trivially fixed upstream but it is not considered important enough to be backported to RHEL 6.5. Thus I'm pushing this bug to RHEL 6.6 (and setting Upstream keyword to indicate we have patches upstream) for now. If you don't agree with this resolution, please, give us reasons which you think are strong enough for us to reevaluate the decision not to backport patches for this bug. Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. |
Description of problem: When tuning memory parameters at domain shutoff, config xml is updated with <memtune> part, but when live tuning domain memory parameters, setting is done without live update domain xml. Version-Release number of selected component (if applicable): libvirt-0.10.2-18.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.352.el6.x86_64 kernel-2.6.32-356.el6.x86_64 How reproducible: always Steps to Reproduce: 1. tuning memory parameter when domain is shut off # virsh destroy libvirt_test_api Domain libvirt_test_api destroyed # virsh memtune libvirt_test_api --swap-hard-limit -1 --soft-limit -1 # virsh memtune libvirt_test_api --config hard_limit : 0 soft_limit : unlimited swap_hard_limit: unlimited # virsh dumpxml libvirt_test_api ... <memtune> <soft_limit unit='KiB'>9007199254740991</soft_limit> <swap_hard_limit unit='KiB'>9007199254740991</swap_hard_limit> </memtune> ... 2. tuning memory parameter when domain is on # virsh start libvirt_test_api Domain libvirt_test_api started # virsh memtune libvirt_test_api --live hard_limit : 25417216 soft_limit : unlimited swap_hard_limit: unlimited # virsh memtune libvirt_test_api --swap-hard-limit 25417216000 --soft-limit 2541721600 --live # virsh memtune libvirt_test_api --live hard_limit : 25417216 soft_limit : 2541721600 swap_hard_limit: 25417216000 # virsh dumpxml libvirt_test_api ... <memtune> <soft_limit unit='KiB'>9007199254740991</soft_limit> <swap_hard_limit unit='KiB'>9007199254740991</swap_hard_limit> </memtune> ... live update did not update the domain xml, it remains as set when domain is off. Actual results: memtune did not live update domain xml Expected results: memtune should live update domain xml Additional info:
