I had my host freezing when I forgot to limit memory utilization in the ZFS. It does not matter what eats into your host RAM - since qemu is just a regular userspace process, it's memory needs (ie those of the guest system) are not "prioritized" as more essential than any other userspace process. If your host does not have enough memory, then the more you allocate in qemu (or libvirt) to the guest system, the more probability that qemu will run out of RAM, effectively freezing the guest OS. At least, this is what it would appear to be (it might be simply swapping, but that slows down guest execution speed by orders of magnitude, so it is effectively frozen)</div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);">B. </div> <div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br style="display:initial"></div> <div style="font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"></div> <table width="100%" style="background-color:white;border-spacing:0px;"> <tbody><tr><td colspan="2" style="font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"> <div style="border-style: solid none none; border-top-color: rgb(181, 196, 223); border-top-width: 1pt; padding: 3pt 0in 0in; font-family: Tahoma, 'BB Alpha Sans', 'Slate Pro'; font-size: 10pt;"> <div><b>From: </b>Berillions</div><div><b>Sent: </b>Friday, 7 October 2016 20:00</div><div><b>To: </b>Jayme Howard</div><div><b>Cc: </b>martin@schrodt.org; vfio-users</div><div><b>Subject: </b>Re: [vfio-users] Win10 Guest, stability is horrible and freeze quickly</div></div></td></tr></tbody></table><div style="border-style: solid none none; border-top-color: rgb(186, 188, 209); border-top-width: 1pt; font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"></div><br><div id="_originalContent" style=""><div dir="ltr"><div>Very very very things.
