Subject Re: [VOTE] Apache CloudStack 4.12.0.0 [RC1]
Date Fri, 08 Feb 2019 17:30:57 GMT
Hi all,

A bug was found when live migrating KVM VMs among local storage with the IO
bursting. The issue is due to the VM's XML file being edited during the
migration process, removing the IO bursting configuration.

Example. A VM with a service offering limiting its IO would have a section
on its XML as the following:




*<iotune>    <write_iops_sec>500</write_iops_sec>
<write_iops_sec_max>5000</write_iops_sec_max>
<write_iops_sec_max_length>60</write_iops_sec_max_length></iotune>*

After live migrated, the VM loses the <iotune>...</iotune> section on its
XML, therefore, having no IO limitations.

Such an issue is critical and I am classifying this bug as a BLOCKER.
I will be submitting a PR fixing it soon. Therefore, next week we will spin
out an RC2 for voting.

Please let me know if there is any other issue to be addressed for RC2.

Regards,
Gabriel.
