Hello,
Why does git commit f400f2993b52e820d0da24a2e49a8fdfab0d2827, make
xen-network-common.sh set a static MAC address for the virtual device
as shown below?
ip link set dev ${dev} address fe:ff:ff:ff:ff:ff || true
I see the high order byte is 0xFE, which has the broadcast flag unset,
thereby s
Hello,
I see that in the xl binary in xen 4.13.0, the acquire_lock() and
release_lock() functions are only called from create_domain() in
xl_vmcontrol.c, so I assume the lock provides inter-PROCESS
synchronization in the case that multiple instances of xl are running
and creating multiple domains c
Hello,
I see oxenstored running at 100% CPU on a busy Xen host. This article (
https://xenproject.org/2014/05/01/9124/) says that the maximum number of
VMs supported by oxenstore is 160. What is the technical reason for this
limit? Doesn't the Xen hypervisor support more than 160 concurrent DomUs?
Hi All,
I am running a userland debugger in Windows 10 HVM on Xen 4.16 on an Intel
chip. I noticed when I set a hardware breakpoint (which writes to the DR0
register), Windows 10 crashes. This crash reproduces both with and without
viridian enabled in the DomU cfg file.

Hello,
I am running xen 4.13.0 hosting many DomUs started in a short amount of time,
but not all of them are accounted for by xentop:
183 domains: 2 running, 0 blocked, 92 paused, 0 crashed, 0 dying, 0 shutdown
Only 94 of the 183 VMs are accounted for, and the STATE column for many of the
VMs s
Hello,
Has anyone gotten a Windows10 (Version 1709 of later) kernel debugger
attached when running the Windows10 debugger VM and the Windows10 debugee
VM on Xen 4.13.0 hypervisor? I am getting a "NIC hardware initialization
failed" error. I tried the suggestions in the discussion here (
