If this chapter sends any single message clearly, it should be this: optimizing the I/O performance of a VM in Proxmox VE involves carefully considering and combining three components, each with a very rich set of options—tuning a VM to perform optimally and with the features you want is a complex balancing act.
Consequently, a list of helpful resources is provided here so each of us can pursue more information based on our specific needs. The first two resources have rich chapters on virtual disks. The third is a work in progress that's thoroughly committed to virtual disk documentation:
- Hands-On Virtual Computing, Ted Simpson, Cengage
- Virtualization from the Desktop to the Enterprise, Chris Wolf, Apress
- The Linux Sysadmins Guide to Virtual Disks: From the Basics to the Advanced, Tim Bielawa, http://lnx.cx/docs/vdg/output/Virtual-Disk-Operations.pdf.
