qemu-stubdom was stripping the prefix from the "params" xenstore key in xenstore_parse_domain_config, which was then saved stripped in a variable. In xenstore_process_event we compare the "param" from xenstore (not stripped) with the stripped "param" saved in the variable, which leads to a medium change (even if there isn't any), since we are comparing something like aio:/p...

Hi, This issue only happens on my IA32E VMX domain. IA32 VMX domain is okay. I am trying VBD disk in IA32E VMX domain. I used following disk configuration to create an IA32E VMX domain. disk = [ ''file:/mnt/disk1.img,hda,w'', ''file:/mnt/disk2.img,hde,w'' ] After creating VMX, its keyboard can not be used properly. For example, if pressing

Hi list, Recently I was debugging L2 guest slow booting issue in nested virtualization environment (both L0 and L1 hypervisors are all Xen). To boot a L2 Linux guest (RHEL6u2), it will need to wait more than 3 minutes after grub loaded, I did some profile, and see guest is doing disk operations by int13 BIOS procedure. Even not consider the nested case, I saw there is a bug reporting normal VM

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and
