| #21250 | invalid | I can't start virtual machine with macOS | ||
| Description |
My systems: Win 11 AMD Ryzen 7 5700U with Radeon Graphics 16 GB RAM |

| #4062 | fixed | host OS cpu always is above 50% | ||
| Description |
I have linux debian squeeze as host os cpu: amd64 dc mem: 4gb virtualbox-2.2.2-46594_Debian_lenny from http://download.virtualbox.org/virtualbox/debian (not virtualbox-ose) (same problem was with virtualbox-ose from debian repo) I have installed windows 2003 server as guest os ( ram 512mb, video 8mb, acpi on, vt on, 1 network interface). Is works fine. host's (linux) cpu load is near 2-3% while guest os idle. If I start few programs ( openoffice, drweb, winrar, etc ...) cpu load of host (linux) jums to ~100% and when programs started it returns to 2-3% cpu load of guest (windows) also falls to 0-1%
Problem: when I run this (installed) program on guest OS (windows) I get above 50% of cpu load on my host OS (linux) and 0-1% on guest OS (windows), the same thing if I run some more programs (openoffice etc.) but when I close qip, load gets to normal (2-3%) on host OS maybe this is qip specific but why guest OS does not show great cpu load or maybe this is virtualbox hardware specific when I start other guest box (winxp) both guests do not get more than 5% of cpu on host OS (linux) when i close that second guest (winxp) cpu load return to above 50% on host OS same thing happens when qip runs on winxp |

| #2278 | fixed | Solaris performance counter library (libcpc) does not work correctly | ||
| Description |
The Solaris CPU performance counter library (libcpc) does not work correctly, yet also fails to return any error codes. If the CPU's performance counters cannot be used, libcpc should be notified so that it can return appropriate error codes. For example, my host system had an AMD Opteron, so I attempted to use the cpu clock counter BU_cpu_clk_unhalted via the Solaris cputrack utility. When I did so, all zeros were reported indicating that Solaris was not actually getting access to the specified CPU counter. > cputrack -c BU_cpu_clk_unhalted gzip core time lwp event pic0 1.017 1 tick 0 2.019 1 tick 0 3.026 1 tick 0 4.038 1 tick 0 5.029 1 tick 0 6.030 1 tick 0 ... > uname -a SunOS opensolaris 5.11 snv_86 i86pc i386 i86pc Solaris > psrinfo -pv The physical processor has 1 virtual processor (0) x86 (AuthenticAMD 20F71 family 15 model 39 step 1 clock 2613 MHz) AMD Opteron(tm) Processor 152 |
