Let me start by reading through the problem description carefully. + +The user reports that when using QEMU with KVM and RBD (RADOS Block Device) as a disk backend with client caching enabled, there's a significant increase in memory usage on the hypervisor. They mention that running 'fio' inside the VM causes the QEMU process to consume much more memory than expected—reaching 250% overhead in production scenarios and about 3GB for their test VMs. + +Looking at how they reproduce it, they set up a VM with an RBD-backed disk, install Ubuntu and fio, then run specific fio tests. They monitor the hypervisor's QEMU process memory using commands like 'virsh dommemstat' or checking /proc/<PID>/status for RSS (Resident Set Size). Without RBD caching, the issue doesn't occur. + +They also note that there's an existing Ceph bug report but can only reproduce it with QEMU. Directly running fio with rbd engine doesn't cause the same high memory usage. + +Now, considering the categories provided: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +The issue is related to QEMU's handling of RBD with client caching, which impacts memory usage. Since RBD interacts with storage and caching mechanisms in QEMU, it likely involves how the hypervisor (QEMU/KVM) manages resources when using block devices. The high memory consumption suggests a performance or resource management problem specific to the hypervisor's interaction with RBD. + +Looking at the possible categories, 'hypervisor' seems appropriate because the issue occurs within the hypervisor environment (QEMU/KVM), dealing with how it handles disk I/O and caching, which affects memory usage. Other categories like 'performance' might also fit, but since it's specifically related to QEMU's role as a hypervisor interacting with block devices, 'hypervisor' is more precise. +</think> + +hypervisor \ No newline at end of file |
