The disclosure provides a logical address allocation method, apparatus, electronic device and storage medium. The method includes: receiving a first request sent by a target virtual machine unit, the first request being used for registering a logical address of a submission queue entry of the target virtual machine unit; performing a hash operation based on the first request to obtain a first hash value indicating the submission queue entry; acquiring a target hash table corresponding to the target virtual machine unit, and querying the target hash table based on the first hash value to obtain a target hash bucket to which the first hash value belongs; acquiring, based on a hash bucket identification of the target hash bucket, a target logical address corresponding to the hash bucket identification from currently available logical addresses; and registering the target logical address as a corresponding logical address to generate the submission queue entry.

Embodiments of the present application relate to a method, a bridging device, a system and a medium of virtualization processing of a storage device. The method comprises: receiving an initial access request to a virtual disk sent by a virtual machine user; translating the virtual address corresponding to the virtual machine to a first physical address corresponding to a host based on a preconfigured address mapping relationship; translating the virtual access address to a second physical address corresponding to the storage device based on a preconfigured virtual partition mapping relationship; and generating a target access request based on the first physical address and the second physical address, and sending the target access request to the host, so as to cause the host to perform information interaction with the storage device based on the target access request.
