+<think>
+Okay, so I need to classify this bug report into one of the given categories. Let me read through the report carefully and understand what it's about.
+
+The user is talking about KVM guests using LVM-backed drives experiencing high iowait times on the host system when there's moderate disk I/O. They mention that KVM defaults to writethrough caching, which causes poor performance. The suggestion is to explicitly disable caching for better performance.
+
+Looking at the possible categories: device, graphic, socket, network, KVM, etc. Since the issue is related to how KVM handles disk caching with LVM-backed drives, it's definitely about KVM behavior. It's not about graphics or networking; it's more about storage and I/O handling.
+
+The user references upstream discussions on qemu-devel and other mailing lists, indicating that this is a configuration or default behavior in QEMU/KVM. The problem lies in the caching mode for block devices, which affects performance but not data integrity as both writethrough and none are considered safe according to the manpage.
+
+So the bug report isn't about a crash or a specific feature request; it's more about adjusting defaults for better performance. However, the issue is tied to how KVM handles storage settings by default when using LVM, which falls under KVM's configuration and behavior.
+
+Therefore, the appropriate category for this bug is "KVM."
+</think>
+
+The issue is related to the default caching mode in QEMU/KVM affecting performance with LVM-backed drives. Since it pertains to how KVM handles storage configurations by default, the correct classification is:
+
+**KVM**
