Subject: [PATCH] qemu_domin: Account for NVMe disks when calculating memlock
|
||||
limit on hotplug
|
||||
|
||||
During hotplug of a NVMe disk we need to adjust the memlock
|
||||
limit. The computation of the limit is handled by
|
||||
qemuDomainGetMemLockLimitBytes() which looks at given domain
|
||||
definition and accounts for various device types (as different
|
||||
types require different amounts). But during disk hotplug the
|
||||
disk is not added to domain definition until the very last
|
||||
moment. Therefore, qemuDomainGetMemLockLimitBytes() has this
|
||||
@forceVFIO argument which tells it to assume VFIO even if there
|
||||
are no signs of VFIO in domain definition. And this kind of
|
||||
works, until the amount needed for NVMe disks changed (in
|
||||
v9.3.0-rc1~52). What's missing in the commit is making @forceVFIO
|
||||
behave the same as if there was an NVMe disk present in the
|
||||
domain definition.
|
||||
|
||||
But, we can do even better - just mimic whatever we're doing for
|
||||
hostdevs. IOW - introduce qemuDomainAdjustMaxMemLockNVMe() that
|
||||
behaves the same as qemuDomainAdjustMaxMemLockHostdev().
|
||||
|
||||
There are subtle differences though:
|
||||
|
||||
1) qemuDomainAdjustMaxMemLockHostdev() can afford placing hostdev
|
||||
right at the end of vm->def->hostdevs, because the array was
|
||||
already reallocated (at the beginning of
|
||||
qemuDomainAttachHostPCIDevice()). But
|
||||
qemuDomainAdjustMaxMemLockNVMe() doesn't have that luxury.
|
||||
|
||||
2) qemuDomainAdjustMaxMemLockHostdev() places a
|
||||
virDomainHostdevDef pointer into domain definition, while
|
||||
qemuDomainStorageSourceAccessModifyNVMe() (which calls
|
||||
qemuDomainAdjustMaxMemLock()) sees a virStorageSource pointer
|
||||
but domain definition contains virDomainDiskDef. But that's
|
||||
okay, we can create a dummy disk definition and append it into
|
||||
the domain definition.
|
||||
|
||||
After this, qemuDomainAdjustMaxMemLock() can be called with
|
||||
@forceVFIO = false, as the disk is now part of domain definition
|
||||
(when computing the new limit).
