Subject: [Bug 199727] CPU freezes in KVM guests during high IO load on host
Date: Thu, 01 Feb 2024 19:56:53 +0000 [thread overview]
Message-ID: <bug-199727-28872-rfa1G8PEAg@https.bugzilla.kernel.org/> (raw)

--- Comment #24 from Gergely Kovacs (gkovacs@gmail.com) ---
To be clear, in our experience aio=threads and iothread=1 solved all VM freezes
on local storage, regardless of the VM running from SATA/SAS HDD or SSD, or
NVME SSD, so it's a great mitigating step. Ceph is not solved for us either,
therefore using Ceph is still not recommended for KVM storage until this bug is
actually fixed (instead of mitigated).
